More recently maximum speed standard 2G (474 kbps) seemed something incredible. Today, the active phase of covering huge areas with the fourth generation network - 4G, is taking place, which allows you to broadcast information at a speed of over 100 Mbps. The 4G network works properly in all major cities, and outside the city (not everywhere) the 3G network is perfectly caught, providing data transfer at speeds up to 3.6 Mbps.
The router independently selects the network available for connection
Mobile Internet is an excellent solution for those places where there is no possibility of a wired connection, for business trips and trips to other regions. And in this regard, the Tele2 operator has a number of advantages, as it demonstrates a distinctive quality of communication, despite the fact. which is inferior to the "big three" in terms of coverage area.
Overview and configuration of a 3G router from Tele2
Modems and routers from Tele2 are manufactured by ZTE - it is with such a router that we will get acquainted today. In fact, modern modems and routers (from mobile operators) are almost the same thing. A router is a device that distributes traffic via Wi-Fi technology, and for this a modem must be connected to a computer via USB. But the router, like the modem, will not be able to work without a SIM card that transmits traffic to it.
The 3G router from Tele2 supports not only the 3G network, but also 2G, which allows it to work even where there is no high-speed network coverage. It has an impressive battery, built-in network and battery indicators, as well as a slot for a SIM card and a memory card. Thus, the 3G router from Tele2 is a compact, convenient and efficient device.
Characteristics:
- supported standards: 3G (UMTS) at 900/2100 MHz, 2G (GSM) at 850/900/1800/1900 MHz;
- wireless network interface: Wi-Fi 802.11 b/g/n;
- battery capacity: 1500 mAh;
- size 102x50x13.7 mm, weight 69 g.
As for setting up the router, everything is extremely simple here - just insert the SIM card into the slot and turn it on. Long and persistent attempts to configure the router, which do not always end in success, are in the past. If you have a router from Tele2, then all the necessary settings are already “flashed” in it, and the user does not have to waste time and nerves on absolutely useless manipulations.
After you have turned on the router with the Tele2 SIM card in it, find an access point on your computer and connect to it. You can also connect a memory card with a capacity of up to 32 GB to the device, and thus make it look like an external drive. When connected to a computer via USB, you can transfer files to a memory card and vice versa.
Advantages:
- multifunctionality;
- ease of setup and use;
- compactness;
- work stability;
- huge range of coverage area;
- support for all existing Wi-Fi standards, as well as full support for 2G and 3G data transfer standards.
Do not forget that up to 10 devices can be connected to a Wi-Fi network. This is an impressive advantage in those situations when you need to use the Internet on several devices at the same time.
Overview and configuration of a 4G router from Tele2
A router (or modem, because it would be more correct to call it that) that supports the 4G standard from Tele2 is also represented by ZTE. It works not only with 4G network, but also with 3G and 2G. The 4G modem is even more compact than the 3G version described above, but it does not have a battery - the device is powered by a computer via USB. The memory card allows you to use the device as a flash drive.
In addition, the Tele2 modem does not have the ability to distribute Wi-Fi, however, you can set up an access point from the computer to which the device is connected. This feature is available on almost all laptops and desktop computers, but few people know about it.
Advantages:
- an impressive range of supported communication standards (full support for 2G, 3G UMTS and 4G LTE);
- huge data transfer rate (up to 100 Mbps when stationary);
- multifunctionality;
- work stability;
- ease of setup;
- compactness.
Flaws:
- lack of Wi-Fi (as mentioned above, this problem, if necessary, is solved by setting up an access point on the computer);
- no battery.
Setting up a 4G modem is quite simple and does not require the user to know any advanced features. Follow these steps:
- connect the device to the computer - the installation of the necessary software should start automatically;
- if the installation does not start, then go to the "My Computer" section and run on a removable disk (this is our modem) a file called "AutoRun.exe";
- after waiting for the installation to complete, click on the shortcut on the desktop and run the program.
As soon as the connection to the network is established, a corresponding message will appear. If there are any problems during operation, the first thing to do is reinstall the program. If after that the problem is not solved, then contact Tele2 support.
The modem is configured in such a way that if there is no suitable 4G network, it will connect to an available 3G network. If there is neither 3G nor 4G in the place where you are, then the modem will work according to the 2G standard. The speed will drop noticeably, but you can still surf the web. This ensures stable operation of the Internet even in situations where the user, for example, is traveling by train.
Conclusion
Comparing the characteristics and capabilities of routers and modems operating on two different network standards, it is safe to say that 4G is better than 3G. However, choosing 4G is not always the right decision. If you plan to use mobile Internet in a region where 4G LTE coverage does not even smell, then buying a modem that works on 4G is pointless. In this case, a 3G router is enough.
The choice of 3G or 4G routers should always be approached sensibly. It is necessary to be guided by data on the quality of communication and coverage in the region where you plan to use the device.
Signal transmitters from Tele2 in 4G and 3G format are mobile or stationary devices endowed with a number of advantages in comparison with wireless modems. A wider range of features and the ability to work with multiple devices, without using a PC or laptop, are the most important advantages of compact Tele2 routers. A user who wants to connect to the network using such a device must purchase the product itself, a SIM card, and connect to the selected Tele2 Internet tariff plan.
Model range of routers from Tele2
Users can purchase a router with third and fourth generation communication support from Tele2 in the Tele2 online store. Tele2 cooperates with trusted manufacturers of electronic products.
4G routers
On the Tele2 website, customers can see only two types of devices - a 4G USB modem and a 4G WiFi Tele2 router, used to transmit a signal through a third generation connection. The devices have proven to be excellent helpers for accessing the Internet while traveling and in areas where there is no 4G coverage and access to a fixed connection. 
Important qualities of a 4G transmitter:
- The price for a product with a SIM card is 2490 rubles;
- Type of cellular communication - GSM;
- Frequencies - 850/900/1800/1900 MHz;
- Support UMTS/HSPA+900.2100MHz;
- The product functions only with a branded SIM card;
- Bandwidth up to - 100 Mbps;
- The device is compatible with all types of MAC OS and Windows OS.

Features of operation, activation and use of 4G routers
The modem is connected by connecting via the USB connector of the PC. By going to the website of the mobile operator, the user can get acquainted with the traffic limits of the selected tariff plan, many of which do not imply unlimited use.
4G router allows you to provide wireless Internet to ten devices simultaneously: smartphones, laptops, tablets. The signal to the router comes through the SIM card, and then it is distributed to the connected devices. The router is configured automatically, immediately after activation.
4G routers
Compound model range 4G signal transmitters from the network are more saturated than those of previous class products. There are: modems, routers, stationary substations, and kits for creating WiFi zones in large spaces. 
Important characteristics of the main types of 4G transmitters:
Detailed information about the device used can be obtained on the Tele2 portal. And in the personal account, the client can change tariff plan and access codes.
The ability to make and receive calls via Wi-Fi from your phone number is now “in the subject”, since one of the most popular situations is calls in international roaming. It's good that they launched before the start of the New Year's travel season. Also to compensate for the lack of coverage in the subway and in problem areas. There are a number of limitations and inconveniences, but it works and may well come in handy
Wi-Fi calls
An interesting and useful thing, in some cases it can be very “fit”. The installed and running application allows you to make and receive calls via the Internet, for this a Wi-Fi connection is used. The application also knows how to send and receive SMS messages. Not to be confused with VoWiFi technology (Voice over WiFi), with VoWiFi, the smartphone fully works in WiFi networks like in a cell phone. In our case, "Wi-Fi calls" uses the data network to "transport" voice and SMS in both directions. For your interlocutor, nothing changes: calls / SMS come to him from your number, and he also calls to your regular Tele2 number. The service is currently available only in the Tele2 network of the Moscow region.
The closest analogue is a similar MTS Connect solution, which was launched in the Moscow region exactly a year ago, you can read our review. The Tele2 option is simpler and does not have additional functionality that the MTS application is literally stuffed with. Is it good or bad? Hard to say. It is necessary to actively use both and compare. In theory, something simpler should work more stable, but this is not always the case.
You can download the WiFi Calls app from the App Store or Play Market, Android (version 4.0 and above) and iOS (version 7.0 and above) are supported. Version for Android smartphones.
For whom?
You do not receive additional financial benefits, money for calls is debited according to your tariff. Or, respectively, minutes/SMS from the package. Free calls between users of this service are also not provided. Your main advantage home tariff, which you use when calling from anywhere, even from Australia. In international roaming, you can save money, and at work it can be useful and practical.
In the presence of a Wi-Fi network, the issue of coverage in problem areas is solved. Relevant for the Moscow region, and, I'm afraid, will be relevant for a long time. Even in areas with good coverage, everyone has problem points, basements and vice versa, the upper floors of high-rise buildings. Tele2 base stations are often located in Moscow and "shine" low.
Communication in the subway. This is a valuable plus for Moscow Tele2 subscribers. I read complaints like “does not work!” and “does not work well”, but there are also many positive reviews. If it works, but not well, I would first advise you to avoid the cars in the middle and try to enter closer to the beginning or end of the train.
Last time during the discussion there was a popular topic: “Why on earth should I also pay for the Internet ?! The operator has problems with coverage, and he wants to solve them at my expense! The same was written when discussing femtocells. If you have no problems, then you really do not need this service, except in roaming. If problems occur, then you can try to change the operator or get by with these “WiFi calls”, it’s a master’s business. What-no, but a solution that is free and working, although working and not perfect. You can still write complaints and be indignant, but this is not very effective. The cover that miraculously appeared after complaints is more often a coincidence.
Peculiarities
For many, the main disadvantage is the mandatory binding to a SIM card with a valid Tele2 contract. For the recipient of the call, a call from the application is no different from a regular call from the owner's phone. You can install the application on any device, but it will not work without a Tele2 SIM card. Moreover, the application will not work even in a device with two SIM cards if the Tele2 SIM card is installed in the second slot. Why did they do that? The reasons are obvious. Firstly, binding to a SIM card guarantees the correct location of the caller. For example, cellular operators, at the request of the relevant authorities, are required to provide information, including the place where the call was made. Secondly, by separating the application from the SIM card, we get the opportunity for several people to use one “instance” of the tariff, this is unprofitable for the operator. In fact, linking an application to a SIM card works like a prohibition on sim card cloning.
When the application is activated, some services are disabled. Personally, I feel sorry for "You called", it's inconvenient without it. There is a suspicion that after the removal of the program, the “You have been called” service will have to be reconnected through the Personal Account. About permission to determine the location, see above, and access to the camera is needed, most likely, to add a photo to a contact. Upon activation, you will need access to the Internet on the SIM card that you link to the application. Without this, the service cannot be activated. Why Internet from a SIM card during activation? Too lazy to guess, but there must be reasons, they didn’t do it out of harm? For example, to disable services upon activation, to determine the number / user without any SMS and passwords.
You can only call through WiFi connection, it is impossible to use data transfer from a Tele2 SIM card or another operator for this. An unfortunate limitation. It would be tempting to use another operator's SIM card to get the Internet, and make and receive calls from your own number. Or even use the new Tele2 option “Internet does not rest” on your SIM card for this when traveling.
There is no handover when calling if you left Wi-Fi zone during a call, the connection will be disconnected, and not switched to the cellular network. Switching to another Wi-Fi point without interrupting the connection is also not possible.
Impression
It was easier for me, I went through all these activation and installation suffering with the MTS Connect application and was mentally prepared for the fact that it was unlikely to work “with a half kick”. And I repeat: for authorization, you need the Internet from an authorized Tele2 SIM card, on a dual SIM card, this SIM card must be in the first slot, it will not work without a full set of permissions. Android versions 4.0 or higher and iOS versions 7.0 or higher are supported. Also, the Wi-Fi signal should be good. Yes, not every Wi-Fi is suitable, as it turned out during the testing process.
Believe me, I read the description carefully, carefully read all the warnings. And still, this thing was configured for me only on the third attempt. The reason for science is unknown, I did not change anything in the settings and did not try to reinstall. And if on the fifth try? I suspect that some of the complainers simply did not "try" the required number of times.
Then the device did not like my home Wi-Fi. Calls do not go through, the phone beeps and gives the message "network unavailable". After the 10th attempt to call from / to, I sat down to think what could be changed, I started from the access point. Miraculously, everything immediately worked on another router with a Beeline sim card. What did he not like about the home router? It seems that the signal level was not bad either ... In general, you need to keep in mind the possibility of such a “plug”.
There are no complaints about voice transmission, the quality is at a good level. It seemed a little muffled and noticeably quieter than with a direct telephone connection. But not critical. SMS arrived instantly. The collected connection success statistics are about 20% only on the second attempt (dialling the number immediately), not once on the third. The remaining 80% from the first. I watched with interest the data transfer rate indicator, the numbers are different. Seen minimum flow - 35-45 Kbps, maximum - 140-170 Kbps during the conversation. Most often in the range of 70-90 Kbps. It is not so demanding on connection speed. Wi-Fi from the “wire” is desirable, but it also works fine via LTE, without delays and “stuttering”. As in any ip-telephony, the response time (ping) is more important than the speed in the data channel.
There are few settings, and they are all intuitive. You can allow the application to work only with voice (without receiving / sending SMS), you can disable autorun after turning on the phone. Special thanks to the developers for the "Exit Application" menu item.
It's a pity that you can only make calls from the application via Wi-Fi, in certain scenarios you will have to use mobile router or a second phone. Probably, some positive can be found in the fact that if you already called from the application and you succeeded, then you probably called via Wi-Fi.
Summary
The purpose of the service is described in detail in the "For whom" section, although there may be other scenarios. You need to understand that this is not a universal communication environment and not another "Skype Killer". This is an additional tool that allows you to fix local problems or solve some specific problems. In this capacity, the program should be considered, nothing more. And, of course, there will be many fair grievances on the topic “why only for Moscow?!”.
It has become a habit for us to be constantly connected using the services of a suitable mobile operator. In the event that access to the network is limited and we cannot make calls, there is a feeling of isolation. Tele2 found a way out of this situation, albeit partially. He provided an opportunity to be in the access zone where there is no network coverage, but the Internet works. This opportunity appeared thanks to the service provided by the operator, called "WiFi-calls".
Why there may be no connection
Coating given operator there is not everywhere, but, nevertheless, there may be a connection of other providers. Provided that the problem arose temporarily due to malfunctions, there is an agreement between the operators to provide roaming. The subscriber can register. In those areas where Tele2 action is not observed at all, roaming of national importance is automatically connected. In connection with the instructions of the FAS, the prices have been reduced.
You will not be able to receive or make a call if you cannot register mobile device online. But also this problem solvable. The method is simple but interesting. It is enough to connect to any available network system and connect Wi-Fi calls to Tele2. This option is suitable where you can use any access point (wireless).
Even if you experience temporary difficulties related to the operation of the cellular network, as a result of which you cannot get through, from now on they will not bring you any inconvenience. If you detect a lack of network signal, simply connect to Wi-Fi (at home or at work), launch a special offer and use the connection as usual.
Service Description
To call in this way, you must use the appropriate application from this operator. At the moment of joining the wireless Internet, calls are made thanks to it. There is also a minus - with a very bad signal, the connection is interrupted. You can download the application for using "WiFi calls" in the AppStore and the Play Market. There is no charge for this.
It should be noted that only users of Moscow and the region have the opportunity to call via Wi-Fi. People in other regions of the country, unfortunately, are deprived of such a bonus. No less significant drawback can be called another moment. When the application starts, some functions stop working, in particular:
- "Voicemail" - you will not be able to leave a message under any circumstances.
- Forwarding - the set settings will not help.
- "Who called" - a service designed to receive notifications of missed calls.
All this is offset by the fact that you can always remain in the access area, even if the Tele2 network is not located. The only thing to do is to find Wi-Fi.
Payment for communication services is as simple as possible. It corresponds to standard billing, similar to calls made from Moscow. But the most interesting thing is that in this way you can save a lot while being abroad. On this moment There are no time limits for this.
Service connection
You do not need to contact the office, go to Personal Area to enable the option. It is enough to download a special application called "WiFi calls" to the device. After its activation, calls will be received through Wi-Fi. To return to work in the standard network, it is enough to disconnect from the point or disable the service in use. No further settings are required.
It should be understood that the operator is not responsible for the quality of the connection via wireless Internet. This is the scope of the administration and communication providers that you use. If problems suddenly arise, it makes no sense to contact the Tele2 service department. You need to contact the provider providing the Internet connection.

Despite the fact that the cellular coverage of the leading mobile operators in Russia is of sufficient quality, it is often possible to find yourself in areas where communication simply does not take.
Fortunately, this is no longer a problem if there is a Wi-Fi point nearby and access to it. So, recently, Tele2 began to implement the Wi-Fi calls service, which we will consider in our today's article.
What is the advantage of the option
This feature allows Tele2 subscribers to make calls to any numbers and receive incoming calls even if they do not have a cellular signal. For this purpose, a Wi-Fi signal is used and mobile app.
The billing conditions for calls made and received via Wi-Fi are identical to the billing conditions for calls in the home region. This allows you to greatly reduce roaming costs, because on holidays at sea or on trips, almost all hotels now have wi-fi.
Tele2 service "WiFi calls": detailed description
To gain access to the use of the service, subscribers need to download and install the appropriate application on their smartphone. To date, versions of the application exist for iOS and Android devices.
After installing the application on the device system, you will need to go through a short setup procedure, following the prompts displayed on the gadget's display.
Note that when the application is running and an active connection to a Wi-Fi access point, all calls coming to the mobile device, or outgoing from it, will be made through the "WiFi calls" application. This condition remains active even if the application is running but minimized. If you want to make a call via standard cellular networks, the application must be closed or disconnected from the Wi-Fi point.
Conflict with other Tele2 services
Before connecting the WiFi calls service, remember that it conflicts with other offers from Tele2. It's about about the "Call Forwarding" options, as well as "Who called" and about the voice mail service. If "WiFi calls" are activated, these services will be automatically disabled.
If over time you want to return access to the use of these options, you will need to remove the application for making calls via Wi-Fi from your smartphone, and then re-activate all the services you are interested in in
