There are situations when you need to find out information right now. For example, you need to find the address or phone number of a store, find out how to get to the right house, translate the phrase you heard, or simply remember the name of the salad that you ate at the restaurant yesterday. The fastest and most real opportunity to get answers to all questions at any time of the day is to go online using your phone.
Benefits of mobile internet
Mobile Internet has a lot of positive features that greatly simplify life:
- allows you to view video files and pictures, read books online without turning on your computer or laptop, being away from home;
- is quite inexpensive;
- helps to occupy free time;
- gives answers to all questions at any time of the day in all parts of the country;
- communication in a social network, conducting business correspondence online.
How to set up internet on your phone
Today, manufacturers are releasing phones that already have a built-in function. wireless wifi or mobile internet. To use them, you do not need any additional programs or devices. Mobile Internet is useful precisely in those conditions when you are in a place without access to Wi-Fi.
If the wireless network on the phone works regardless of the choice of the operator, then Mobile Internet still attached to it. The Internet provider's website lists all Russian operators that provide access to mobile Internet. Everyone can get acquainted with tariff plans and offers. There are also numbers of operators through which you can contact them and ask in detail about the services.
Each operator offers different tariffs for mobile Internet. Some accrue MB of Internet daily in a limited amount, others offer to order unlimited for a month. There are additional service packages, where, for example, for an additional fee, they offer to add the amount of MB.
The pricing policy also depends on the speed of the mobile Internet. Now operators are creating profitable offers for their customers. Using the site search system, you can find what tariff packages are offered by operators. For example, it may be a set of free calls, messages and the Internet, which is provided daily for a small fee. Free search internet provider http://prov.telekomza.ru/providers/ in your home: Telekomza.ru
So, the first thing you need to know for manual configuration is the operator, the type of network that it supports at the current tariff and the data for subsequent introduction into the APN, namely, the operator's settings for manually configuring the Internet and MMS messages.
Choosing a mobile operator and type of Internet connection should not cause any difficulties, but with APN settings, things may not go smoothly. If there are problems with them, you need to go to the official website of the mobile operator, select the current tariff and find links to Internet connections.
In order to set up the Internet automatically, you need to go to the "Wireless" tab in the "Settings" menu, then select the "Mobile networks" sub-item, and then select your operator. After a few seconds of processing, the Internet settings and MMS support should be added to the Internet Access Points menu. After that, you just need to go to this menu item, check and activate the settings responsible for the Internet.
Internet connection settings for advanced users
To implement this method, you need to check the APN for any settings with the presence of the operator name and Internet type. If such settings are indeed already in the lists of APN settings, then most likely one of them is the desired type of Internet network.
In order to activate one or another type of settings, just go to the "Internet access points" menu and activate one of the inactive checkboxes on the right side of the screen, each of which is responsible for certain settings.
Sometimes, after buying a new Android smartphone or after connecting to a new operator, an SMS message arrives with ready-made settings for all types of Internet networks or MMS support that can be used on the current tariff.
You should also know
Also an important point in manual configuration is the choice of the type of Internet connection network. It can be selected in the "Mobile networks" submenu - in the same place as APN. If the tariff works only with GSM networks, you should not select the 3G or higher mode, as this can significantly affect the consumption of battery resources.
In addition, in this submenu you can disable the automatic connection of roaming, which is only needed for using the Internet abroad. It would be much better to enable its manual connection, since if the smartphone accidentally connects to the Internet while roaming, the traffic will be charged at greatly inflated rates.
A phone or tablet ceases to be so useful and interesting if you no internet access, social networks, fresh news and the opportunity to get an answer to any question. If, nevertheless, there is a problem with accessing the Internet on an Android device (tablet or phone), you can always find out the cause and fix it.
The very first action that must be taken if it is impossible to use the global network is check balance, often the operator limits access to the Internet with a zero or minimal negative balance, even if there is free Internet traffic. If the balance is positive, but there is no access, we check the device further.
Most phones provide having two sim cards, in the phone settings there is an item "SIM card manager", there you need to select which of the cards will be responsible for accessing the Internet (a situation may arise when it is set in the phone that SIM card number two is responsible for accessing the Internet, and its not there at all).
If the balance is positive, the desired SIM is selected, but there is no access, check if it is enabled data transfer, for this we lower the top curtain on the working screen of the device and turn on mobile data, if the miracle did not happen, then the phone does not have settings.
The easiest way to get automatic settings is to call your mobile operator. There you can also clarify whether you have all the necessary services for accessing the Internet (data transfer service) in your room. The operator number is most often indicated on the SIM card itself or in the service agreement.
There is another simple way to get automatic settings - remove the SIM card from the phone and install it again, the mobile operator reacts to the new SIM registration on the network and sends the settings in the form of SMS messages on its own. Settings are enough install and reboot device. It happens that the device does not support automatic settings (for example, the device is not certified).
If for some reason the automatic settings did not come to you or did not suit you, you must register manual settings.
Manual Internet setup
Open the phone menu and look for "Settings"
Select in the menu "Wireless networks" (or "More ...", or "Advanced") → "Mobile network" (or "Mobile networks", or other similar name) → "Access point" (or "Access points", or " APN").
Press the soft key (touch key) with the image of a square (or the + icon in the upper right corner of the screen), select "Create" or "New access point"
We register the operator settings (access point name, APN, password, username). Video on manually setting up mobile Internet for the main operators of Russia, Ukraine, Kazakhstan, Belarus can be found by Settings are written in Latin. Each operator has its own settings, which can be found on the official website.
Press the soft key (touch key) with the image of a square (three dots in the upper right corner of the screen can also perform this function), select "Save".
Mark the access point with a checkmark.
We reboot the device. An internet icon should appear at the top of the screen.
The settings for tablets and phones are identical.
If you correctly followed all the instructions, then most likely you already use this blessing of civilization and are aware of the latest events. If, nevertheless, difficulties arose and you are unable to cope with them on your own, contact a communication salon or an Internet provider, they will certainly help you.
The ability to “dive” into the Internet at any moment to find the necessary information, check mail or just for fun has become a familiar and even necessary reality of modern life.
It becomes even more offensive when access to the mobile Internet suddenly disappears. And according to the unwritten "law of meanness" this happens just when it is especially needed. So, let's talk about the causes of Internet access failures and the possibilities of its restoration.
Problem in the router
If you do not use mobile Internet (from the operator), but through a router connected to a fixed line, then most likely the reason is a router failure. To restore communication, just turn off and turn on the router, after which the connection is restored.
In order to use secure WiFi connection, you need to connect by entering the machine's LAN password. Without knowing this password, you will not be able to connect to the router and use it to access the Internet.
There is, of course, another way out - to try to make an antenna to receive a free Wi-Fi signal from the nearest distribution point. AT major city it is not difficult to find such a router - cafes and restaurants are usually equipped with them, educational establishments, libraries, some government agencies, etc.
Many "craftsmen" are now using this to access completely free internet, connecting to these distribution points using homemade antennas and signal amplifiers.
Coverage problem
Mobile Internet depends on mobile network coverage, signal strength, station congestion and other factors. Therefore, if the Internet on your mobile phone suddenly disappeared, try:
Check for a network - if it has disappeared, the Internet will not work either;
Check the signal level - too weak a signal may be insufficient for a full exchange of data packets;
Try to open other sites - perhaps the problem is in the address of the site you want to visit.
If you find out that the Internet really does not work due to the lack of a mobile network, nothing can be done - you will either have to change your location and look for an area in which there is a strong reception of the mobile station signal, or put up with the inability to use the usual service.
Phone problem
The more complex the device, the easier it fails - this axiom also applies to mobile phones. There may have been some kind of malfunction in the operating system of your smartphone - to fix it, try turning your phone off and on again. Often after that, the connection is resumed, and you can freely use the Internet.
If this is your first time accessing the Internet from this phone, you need to check the settings and parameters specified in the corresponding section.
All mobile operators send Internet settings automatically, but for some rare models, sometimes you have to manually set the settings. To do this, it is better to contact a specialist in the service department of your mobile operator.
The rarest case is a hardware malfunction, i.e. phone itself. Here, the possibility of recovery can only be assessed by a specialist in the repair of devices.
Account problem
This happens not so rarely - you simply forgot to top up your phone account or mobile Internet account on time, and the operator turned it off as soon as the money ran out.
The problem will be solved as soon as you get to the nearest recharge terminal and deposit the required amount into your account.
Since its inception, many people have had problems with the Internet. Especially when it comes to working with a mobile operator. It is probably very common and unpleasant phenomenon. What to do in cases where the Internet does not work for MTS? There are a lot of options, to be honest. And now we will try to deal with everyone.
Negative balance
Let's start with mobile internet. With it, most often there are failures and malfunctions. So, you picked up the phone and noticed that the Internet does not work for MTS. What should be done in this situation?
For example, for starters - check the balance of your phone. Our today's operator has one rule - only subscribers who have a "plus" on their account can use the Internet. Even if you paid for the selected connection package a month in advance.
Found that you have a negative balance? Just close the debt and wait until you receive a message about unblocking the number. That's all. Now we know how to act if the Internet does not work on the phone ("MTS"). But this is not the only scenario.
Engineering works
Also, failures in working with the World Wide Web at cellular operators can be observed during technical work and prevention. These events have not been announced for a long time. Only if the process is long.
Your Internet does not work on your phone ("MTS")? Then call the service center on the hotline, and then find out what's wrong. Maybe there was some kind of accident, or technical work is really being carried out. Is the answer positive? In this scenario, all you need is patience. When all failures and work are completed, the performance of the Internet and communications as a whole will be restored.
Bad signal
True, not everything is always so bad. Quite often, if the mobile Internet does not work (MTS, Beeline or any other operator cellular communication you), the reason may be a bad signal. That is, you are far from the transmission tower. And because of this, there are failures in the work.
In addition, the cause of this behavior can be a huge load on the network. Even if you are in the city center where the transmission lines give the maximum signal, the Internet may not work. Or do it very slowly. Change your location and also wait a bit. Until the load on the network subsides. Often it is enough just to get away from the place where the MTS Internet does not work well.
Viruses
It is also worth noting that quite often the World Wide Web refuses to work due to the presence of viruses on the gadget. This applies to both phones and computers. In the second case, this phenomenon occurs more often.
In order to get rid of the problem, you will have to scan the gadget, clean it of infection and spyware, and also reboot. After that, check if everything is in order. Does MTS have no internet? Take your phone to a service center. Or to the operator in the nearest office. Explain what you think about infecting the phone. Let them help you there. Often in the case of smartphones and tablets, this is the wisest decision.
If the problems relate to the computer, then you should clean the operating system yourself. This is where an antivirus comes in handy. Scan your computer, find viruses, treat dangerous files. Then delete what's left. Now you can reboot and check if everything works. Not? Then we continue to think further, what is the matter.
Drivers and Settings
In principle, we figured out the phone and tablet. If the Internet does not work for MTS on these gadgets, you should not panic. Just go through all the above solutions one by one. But if we are talking about the home Internet, then you have to try. After all, the connection is through a computer.
And therefore quite often it does not work for users home Internet("MTS" or any other operator) due to the lack of drivers, as well as reset hardware settings. The situation is corrected easily and simply - by installing the software for the modem. All settings will be set automatically.
Where to get drivers? Or from the official website of "MTS", or directly from the kit with the modem. A few minutes of waiting - and all problems are solved. Make sure the whole process runs smoothly. Otherwise, there will be no result from the drivers. In addition, to connect the MTS Internet, you must have content called "MTS Connect" installed. Usually it is installed along with the drivers. If it is not available, find the program for your operating system on the official MTS website.
Hardware question
Sometimes there are situations in which the World Wide Web refuses to work due to a modem malfunction. Or its incompatibility with the operating system. AT recent times this is a fairly common occurrence. This is especially true for users who have upgraded their computer to Windows 10.
Are you having problems connecting "MTS"? Internet does not work? Check if the modem is working. It is advisable to connect it to another computer with exactly the same operating system. Also, pay attention to system requirements to establish contact with your "machine". With their discrepancy, one should not be surprised at the refusal to work. You can change the operating system and retry the connection. If it turns out that the modem is to blame, it will have to be replaced.
In this article, we will look at the easiest ways internet access settings via phone.
Currently, setting up your phone to access the Internet is very simple. All the Big Three operators have come up with a variety of automatic settings for accessing the Internet through the phone.
We will consider both general methods and specifically for MTS subscribers.
The easiest way to automatically configure Internet access through your phone is to call with MTS mobile phone to 0876 (toll-free). All you need to do is just call this number, listen to the autoinformer and hang up. In response, after 2-10 minutes you will receive automatic settings for accessing the Internet via your phone and automatic settings for using the MMS service from MTS.
It is important to understand that there are two types of Internet access:
- WAP GPRS
- Internet GPRS
Internet access via WAP GPRS is ten times more expensive than Internet GPRS. Many JAVA applications will not even work with WAP GPRS for the reason that it will be very expensive, so these applications are specifically limited to WAP GPRS.
To access the Internet comfortably through the phone, they usually use the most popular mobile browser. mini Opera. A lot of people also use the app. Jimm for ICQ. Both of these applications will only work over Internet GPRS.
The method of automatically configuring the phone for accessing the Internet through the number 0876 indicated above will allow you to configure the phone via WAP GPRS. Therefore, it is not suitable for everyone.
To automatically configure the phone via Internet GPRS, you need to send an SMS message with the word internet to a free number 1234 . After that, after 2-10 minutes you will receive automatic settings. Internet GPRS as long as your phone supports auto setup. Most modern models support this method of setting up your phone to access the Internet.
It is worth noting that not all models also support Internet access via, many old models, as well as some budget models, can access the Internet only via WAP GPRS. There are models that allow you to access the Internet via Internet GPRS, but do not support automatic settings.
In the future, there are plans to publish here detailed manual phone settings for accessing the Internet via phone. Perhaps this will be done at the request of our readers.
If you are faced with the fact that you cannot configure Internet GPRS on your phone, then write about it in the comments.
We need to know:
- Your region
- Your phone model (if you don't know, you can usually see the phone model under the phone's battery)
The second way to set up Internet access via Internet GPRS for free is through a special form. http://mobile.yandex.ru/tune.xml
This method of accessing the Internet through the phone is suitable for both subscribers MTS so for Beeline, Megaphone and other mobile operators.
Just choose your operator, phone model, enter your phone number and click get settings via sms. The settings will come and you just have to save them.
How to understand what settings you have by default Internet GPRS or WAP GPRS. You can see this in your profile settings. Of course, this is done differently for each phone model. Therefore, if you do not understand how this can be done, then you can try running the mini Opera or Jimm application, if it does not start, then the WAP GPRS settings, and if it works, then you have Internet GPRS configured exactly - there is no other way.
This post will be updated. Write what other questions you have about setting up your phone to access the Internet.
Manual settings for accessing the Internet via a mobile phone:
- Sony Ericsson: For example
It is rare that no one has encountered such a problem. It seems that everything should be in order: the phone is working, the SIM card is inserted, the contract with the provider is concluded - but there is no access to the Internet. And just about he was still there, and after a minute - as if it had not happened. A familiar situation, isn't it? If the Internet does not work on your phone, then do not despair and rush headlong to the service center.
With very little effort, you can really cope with the problem and without someone else's help. the Internet on the phone is configured a little differently than on a regular personal computer, and this often causes difficulties for users. What interface elements are responsible for setting up the connection? What are the possible reasons for denial of network access? We will consider all these issues in our note. The most banal reasons get the least attention. And absolutely in vain. Here is a short list of them:
- The Internet on the phone is disabled for non-payment. That is, you have a negative balance in your account.
- The phone does not connect to the Internet because you are out of network coverage.
- The data transfer option has failed.
- In all other respects, a normally working mobile phone did not go through the automatic registration procedure.
The likelihood of the above is quite high. It is by checking these options and troubleshooting these problems that we will begin our fight with the disappeared network.
The simplest tests
First, we check the state of the balance. Each provider offers its own way. Read the instructions or rummage through the contact list - there is usually a corresponding number there. To get account information, type *, then a three-digit code (unique for each operator), followed by the # symbol and press the call button. In response, the display shows the value of the amount available for payment of calls. If the wallet is empty or there is a cash overrun, replenish the account and the Internet will appear.
We will assume that everything is “OK” with the balance. What to do next? We look at the network connection indicator. If it is disabled, it means that you are out of range. The only cure for this is to get out of this place.
All modern smartphone models have a special option. It's called Data Transfer. To get to this setting, do the following:
- Go to the connection settings menu.
- Click on "More".
- Click on "Mobile Network".
- On the screen that opens, check the "Mobile data transfer" box. The figure below is a good illustration:
What to do if there is still no internet? You can try turning your smartphone off and on again. Sometimes it helps. The fact is that 3G networks often stop responding after leaving the subway and in other cases getting into the access zone from places where there is no network. In this scenario, the machine is unable to connect to the network without rebooting.
Restore settings automatically
It happens that the device has lost its network settings. Restoring them is not difficult and can be done in two different ways: get the settings from the operator or perform the configuration manually. Of course, the first method is preferable. Just because it's easier. No need to bother yourself with all sorts of technical details. For some time now, this service has become available from every mobile operator. To download the settings from the provider's server, you need to call a specific number or send an SMS to the number. For Beeline, this is a call to 06503, for MTS - SMS to 1234, Megafon receives SMS to 5049, and Tele2 is waiting for your call to 679.
In response, the operator will send a package of settings to the phone, which will automatically register in the operating system of your phone - that is, you don’t have to do anything with “handles”. If you do not know the "magic" number of your operator, then refer to his website - this information should be there.
Restoring settings manually
Everyone is theoretically capable of setting the parameters manually, but not the one who is not at all friendly with the OS of his smartphone. Here is a brief instruction (for more or less experienced users it should be enough):
- We get to the APN access point settings. Usually through the items "More" => "Mobile network" => "Point access APN».
- We create new point access by clicking the plus sign. A form will open with fields to fill out. Here you will need to set the connection name, username, APN parameters and password to enter the network.
- We take the field values from the following table, it contains data for each operator:
Enter the values in the fields, save and reboot the phone. If, after switching on, the network is still absent, it means that things are bad and you have to go to the specialists. Here, in principle, is all you need to know about why the Internet does not work in your own phone.
Almost all of us have used the Internet at least once in our lives. Modern technologies are developing more and more, which is why we can not only quickly find out the necessary information, but also communicate with people on another part of the world. Now there is wireless wired Internet for PC, but you can also set all tariffs for mobile Internet. Now there are unlimited tariffs that allow you to discover the "World Wide Web" not only at home. If you would like to receive a mobile unlimited Internet, then on internet-obl.net/bezlimitnyi-internet/ you will be able to help. You can choose tariffs, choose the cost of payment that is convenient for you. Consider how convenient and practical it is to have mobile Internet, whether it is worth using it, the main advantages and disadvantages.
Pros and only pros
If you decide whether you need unlimited Internet on your phone, then it is important to know its main advantages. The first advantage is the ability to communicate everywhere: in transport, on the street. That is, you do not need to look for wi-fi points for communication. This is very convenient for those who are used to communicating every day and every minute. This is what concerns ordinary youth. But it is also difficult to do without constant Internet. business people, whose salary depends on timely responses to customers and the like. note that modern technologies also allow you to practically be in any part of the city and country. That is, if you get lost or don’t know how to find a store, you can quickly do it, since you have a phone with mobile Internet at your fingertips. Also today you can connect the mobile Internet to a PC and download the pages completely.
What are the negative aspects
It is also necessary to note the disadvantages of mobile Internet. If you choose high speed internet and unlimited traffic you will have to pay a lot. This is due to the fact that modern Internet tariffs are quite high. Usually the cost is even higher than for regular communication services. The second disadvantage is the speed of the Internet. If you live in big city, metropolis, then, most likely, the coverage will be good and the speed of the Internet will even allow you to watch the video. But for villages and small towns, this option is not suitable. You just pay money to wait 10 minutes for one page to load. It is very expensive for such services.
Looking at them, I realized that it was time to update the material - the second article was written at a time when Yota was working on Wimax technology, and 4g had just appeared, the first one even earlier.
The new article is not only about modems, but about the mobile Internet in general. It is designed primarily for those who have just begun to understand this topic, that is, “experienced mobile Internet users” are unlikely to find something unknown here.
I want to chew on some of the fundamental subtleties associated with the mobile Internet, "put everything on the shelves", so to speak. Let's start.
What do you need to use mobile internet?
- an agreement (and a SIM card) with a certain mobile operator and a connected tariff (tariff option, package), which implies the presence of a certain amount of traffic or access to the network without restrictions;
- a device that will work with this operator and allow you to directly “surf the Internet”, and (or) make it possible to connect other devices to the network;
- everything should happen in the coverage area of the network of the selected operator.
It seems simple, but in reality - there are enough subtleties, let's sort it out in order.
Where will mobile internet work?
It will work within the coverage area of the network of your chosen operator. At the same time, the better the signal level, the better it will work. The signal level is not the only thing that determines the possible speed.
How will mobile internet work?
There are a number of technologies for transmitting data through mobile networks- speed depends on what technology is used in this moment. Each defined technology must be supported by both the device and the operator base station with which it operates. We also do not forget about the signal level.
The speed will depend on:
- what type of network the operator has in the place where you are;
- what data transfer technologies your device supports;
- what is the signal level in the place where you are (I wrote about it separately).
The speed depends on the current load on the network (primarily for cities) and on the weather (on the contrary, this is especially noticeable outside the city, when the distance to the base station is large).
What types of networks and data transmission technologies exist at the moment?
Second generation networks - 2g (GSM). Includes two data transfer technologies:
GPRS- the slowest option. If we are talking about a smartphone or tablet, then when working with GPRS, the “G” symbol lights up next to the signal strength indicator. The "ceiling" of this technology in ideal conditions is only 171.2 kbps. And conditions are rarely ideal. You can't do much with GPRS - e-mail, surfing (it's better with disabled image loading - otherwise you will wait for loading each page for a very long time), instant messengers. About YouTube, listening to music online and other delights modern internet feel free to forget.
EDGE- already better. When working with this technology, the smartphone or tablet will show the letter "E" next to the signal strength indicator. The theoretical "ceiling" for EDGE is 474 kbps. In real conditions, the speed will, of course, be lower, but still - you can count on 150 - 200 kilobits, and this will already allow you to surf (having angelic patience), play some games (many MMOs do not need a wide channel), and etc., but with multimedia content, as before, it will be hard.
Third generation networks - 3g (WCDMA):
This includes actually 3g (UMTS), and when working in such networks, the smartphone or tablet will show the symbols "3g" near the signal strength indicator. The theoretical maximum data transfer rate is 2048 kbps. This can already be called quite adequate network access speed. You can also talk on Skype and watch videos on YouTube.
HSDPA- a more advanced version. Theoretically possible speed is as much as 84.4 Mbps. In the "field" conditions, I was able to see numbers in the region of 5 - 15 megabits. The smartphone, when working with HSDPA, will show you the symbol "H" or "H +".
Fourth generation networks - 4g (LTE)
And so far, the only technology in this category is actually 4g, or, if you use the “official” and not the marketing name, LTE (although not only LTE. If you are interested, see Wikipedia). In theory, 4g supports speeds up to 173 megabits per second for receiving and 58 for uploading. In practice, I was able to “target” 40 megabit reception (although I often see talk about higher speeds on the net).
About devices
To access the network, you can use various devices. It could be:
Modem. Connects to a computer via USB, some tablets also support modem connection - also via USB using an OTG cable (if there is a full-fledged USB port, then without any OTG). Allows you to access the network on the device to which it is connected. If the Internet needs to be distributed, then there are several options. Connect the modem to the router (see the next paragraph). You can distribute from the computer to which the modem is connected, but this requires quite specific settings, especially if you plan to distribute via Wi-Fi. You can, if necessary, distribute via Bluetooth. Theoretically, the tablet to which the modem is connected can also distribute the Internet (additional programs may be required if there is no “portable hotspot” option in the settings).
If the modem was purchased in the salon of one or another operator and carries its identification marks on board, then, with a probability of 99.9%, the modem is "locked", that is, a software restriction is set, due to which the modem only works in the network of its operator. You can overcome this misfortune - the modem can be "unlocked". There is no universal recipe here, so we enter the modem model into Google, add the word “unlock”, and read what we found (most likely it will be all sorts of forums).
Turning not to a communication salon, but to a regular computer store, you can buy a modem that will work with the network of any operator. Keep in mind that it will cost more (maybe even much more) - operators, not infrequently, sell modems, which is called “at a loss” and earn money by selling traffic.
Router + modem. We connect the modem to the router, set up the router - it distributes the Internet - via Wi-Fi, by wire, etc. From the subtle points - the router must have a USB port, in addition, you must first clarify whether a particular router works with a particular modem. You need to look for a list of supported modems on the website of the router manufacturer, where you can also download the latest firmware, which can support new modem models.
Special mobile router. These are sold in communication stores, and are a device that already combines both a modem and a router. Still, not infrequently, there is a battery - so that it can be used in "field" conditions. Like modems, they can be "locked" to one operator. As is the case with modems, in computer stores you can find devices that are not tied to any particular operator.
Cellular telephone. Often, it can also provide Internet access by connecting to a computer or tablet with a wire, or via Bluetooth.
Smartphone or tablet. Most smartphones and tablets (of course, those that support 3g or 4g and have a slot for a SIM card) can act both as a modem, when connected to a computer via wire or Bluetooth, and as a router, distributing the Internet via Wi-Fi. Since we touched on this topic above, I will mention that inexpensive smartphones sold in communication stores under the brands of certain operators are also often “locked”, in two-SIM cards only one SIM card is often “locked”.
Will a 3g modem work in a 4g network and vice versa?
The question is valid not only for modems, but also for any other devices.
Operator networks rarely support just one technology. Often they are supported by everything from 2g to 4g. In the outback there are base stations without 4g, and sometimes without 3g. That is, with rare exceptions (we will consider below), if you see some kind of cell tower, then it is most likely “2g or higher”.
Various devices, most often, also support everything, although it is still quite possible to buy a smartphone or modem in the store that “can” only 2g and 3g.
Other things being equal, there shouldn't be any problems. If you get to a place with a 4g modem (smartphone, tablet) where the operator has 3g coverage, it will simply work in 3g. And even in 2g it will work if you get to a place where there is only such coverage.
If you with a 3g modem (smartphone, tablet) get to a place where the operator has 4g coverage, the device will still work, but again only in 3g. Finally, if you take some old phone that does not even know how to 3g, then it will still work - just in 2g.
There are exceptions to what is described above. For example, the Tele2 network in Moscow and the region is implemented only in 3g and 4g. Or Yota modems - they work only in 4g. And even if you insert a Yota modem SIM card into a "non-Yota" modem that "can" 3g, nothing will work - that's how everything is arranged with them.
Let's take a closer look at the situation with Tele2 in Moscow: if you insert a Tele2 SIM card into some device that can only work in 2g networks, then nothing will work for you.
More complex example- almost all dual SIM devices currently on the market have only one SIM card that can work in 3g \ 4g, while the second one will work only in 2g. This means that when using Tele2 in the Moscow region, you must give the privilege of using 3g \ 4g to this particular SIM card. Under these conditions, you can adequately use the Internet only through Tele2. If you want Internet through a SIM card of another operator, you will have to switch it to 3g \ 4g mode, while the Tele2 SIM will go into the “2g only” mode and simply stop working - I remind you, because Tele2 has no 2g network in Moscow.
Smartphones in which both SIM cards can simultaneously work in 3g \ 4g are still few (google and find out if you need one).
About SIM cards and different devices (will a SIM card from a modem work in a smartphone and vice versa)
Looking through the search queries through which visitors come to my site, I often see something like “is it possible to insert a SIM card from a smartphone into a modem” or vice versa “from a modem to a smartphone”. At the time of writing the previous articles, both questions could be answered in the affirmative, but now the situation has changed.
Technically, you can insert a SIM card from a smartphone into a modem without any problems - exactly the same SIM cards are used there and there. Even if you have a micro-SIM in your smartphone, and a full-size SIM in the modem, you can still insert it by simply pressing it against the contacts in the desired position, since the contact pad is the same size there and there. You probably noticed that SIM-cards are now sold universal - initially it is full-sized, and using pre-saddle cuts, it can easily be turned into micro- and nano-SIM. The piece of plastic remaining after this can be used as an adapter. Decided, from a technical point of view, there are no problems.
There are restrictions of a different nature - along with the appearance of tariffs offering unlimited Internet for a smartphone / tablet, there was also a restriction on the part of operators who are not interested in using SIM cards with such tariffs in modems and routers. As a rule, this is stated in the tariff itself - something like "The SIM card is intended for use in a smartphone / tablet, when used in a modem, Internet access will be limited."
There are also modem tariffs, the use of which in smartphones is limited by the operator. And if not limited, then on some of them voice calls are generally impossible, on others high prices are set for “voice”. Be careful!
The final answer to the questions “is it possible to insert a SIM card from a smartphone into a modem” or “A SIM card from a modem into a smartphone” is as follows: depends on your carrier and tariff plan. If in doubt, call the operator and ask.
About distributing the Internet from a smartphone or tablet
If you have Internet access on your smartphone or tablet, using wire, Wi-Fi or Bluetooth, you can provide network access to other devices - say, a laptop. It is very convenient on the road. This is how I use the Internet at the dacha on weekends, and at home I use the Internet from my smartphone as a “backup channel” - if the wired Internet is turned off, a couple of taps to start the access point on the smartphone - and I'm back online.
That's like all. I hope the article was useful to you 😉
