It has become a habitual phenomenon for us to constantly be in touch, 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
The coverage of this operator 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 the effect of Tele2 is not observed at all, in automatic mode roaming of national importance is 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 your mobile device on the network. But this problem is also 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. At the current time, there are no restrictions regarding this.
Service connection
You do not need to contact the office, go to your personal account in order to activate 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.

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 themselves as 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.
Important qualities of a portable WiFi Tele2 router:
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 up 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
The composition of the model range of 4G signal transmitters from the network is more saturated than that of the products of the previous class. 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.
Tele2 has a technology that solves several problems at once. The WiFi Calls app allows you to use mobile communications and SMS wherever there is Wi-Fi. Now you can send and receive SMS, as well as talk on the phone in the Moscow metro (unless, of course, the noise of trains does not interfere) and other places where there is no mobile network, as well as use communication and SMS in any country in the world without paying anything for roaming.
When the "WiFi calls" application is launched, incoming calls and SMS are received as usual if the mobile network is available, but WI-Fi is not. If there is Wi-Fi, calls and SMS are received by the application, and for the one who calls you, such a call will be no different from the usual one. It is necessary to make outgoing calls and send SMS in the absence of a mobile network in Wi-Fi mode through the application.
After installing the application, you need to activate it. To do this, Wi-Fi must be turned off and on. Mobile Internet Tele2. Next, the application asks you to turn on Wi-Fi and select networks through which it can work.
The application works only if the phone has a Tele2 SIM card and it is not disabled in the settings of the dual SIM phone. As soon as the SIM card is inactive, an error message appears and the application requires re-activation.
The application always shows its status in the status bar. When it is inactive (no Wi-Fi connection), a circle is shown, when it is active, a circle with a triangle inside. The application tries to connect as soon as Wi-Fi internet appears. Usually the connection takes about 15 seconds. When the application is active, the phone becomes available and SMS messages are received that could not be received before.
The application copies the list of calls and SMS from the lists of calls and SMS of the phone, while calls received and made via Wi-Fi appear in the phone's call list, and SMS received and sent via Wi-Fi are visible only in the application.
Through some WiFi connections the application is unstable, periodically disconnecting and giving an error. In particular, this was observed when using the MTS home ADSL Internet (formerly Stream).
Application settings.
Wi-Fi networks can be added at any time, in addition, when the application sees that the smartphone is connected to a new Wi-Fi network, it itself offers to add this network to the list.
I checked how the application works on a dual SIM smartphone in various modes. If the smartphone allows you to change the network mode for both SIM cards (and most smartphones can do this now), the application continues to work even if the Tele2 SIM card is set to 2G mode and it does not see the network (in Moscow, Tele2 does not physically have a 2G network). This makes it possible to continue using Tele2 communications in Moscow even when 2G mode is set for the Tele2 SIM card.
The sound quality for calls over Wi-Fi is almost the same as for regular calls over a mobile network.
Calls and SMS through the application are charged in the same way as regular calls and SMS.
I see several applications of the new technology at once:
Use in the Moscow metro. Now the Tele2 network is available only at a few stations, but all cars have Wi-Fi. The WiFi calls app allows you to stay connected in the subway, although you can use it only in the cars, but not on the platforms (the app may not have time to connect to the train's Wi-Fi while it is standing at the platform);
Roaming usage. Now you can make and receive calls, as well as receive and send SMS at home rates, from anywhere in the world by connecting to Wi-Fi.
The ability to use Tele2 mobile communications, where there is no network signal, but there is Wi-Fi (for example, in the basement).
Use in a dual-sim phone when 2G mode is set for the Tele2 sim card.
The main limitations of the technology:
The Tele2 SIM card must be physically present in the phone and be active;
The application does not work through the mobile Internet of another SIM card in a dual SIM phone;
To activate the application, Tele2 mobile Internet is required (there may be problems with this when roaming, so it is important to activate the application before the trip, do not remove or disconnect the Tele2 SIM card. You can turn on "flight mode", activation does not crash).
When the "WiFi calls" application is launched and the smartphone is connected to Wi-Fi, calls and SMS are received through the application, even if there is a mobile network.
The WiFi calling app is available for Android (4.0 and up) and iOS (7 and up). So far, the service has been launched only for Tele2 subscribers in the Moscow region.

The main topic of my blog is technology in human life. I write reviews, share experiences, talk about all sorts of interesting things. I also make reports from interesting places and talk about interesting events.
Add me to your friend list
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 a Wi-Fi network, as in a cellular one. 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. The main advantage is your 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. base stations Tele2 are often placed 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 deleting the program, the “You have been called” service will have to be reconnected via Personal Area. 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 the Wi-Fi zone during a call, the connection will be disconnected, and will not switch to 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 a 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?!”.
