  • This is most often a paid feature;
  • The user will have a long time to understand the settings;
  • It is necessary to have access to a personal account.

This, as a rule, stops many people choosing this way. It is worth choosing it only when there are no other options.

Pay attention! Settings are different for each service provider. It is necessary first to see what operator you use, and then to edit only for its algorithm.


If you start with Tele2, the cost is about 1 ruble per day. You should always check the official websites for more information. Blacklist is regulated by the user. Connection of the service is free, but the fee is quite high.

In order to connect it, you just need to open the program, through which you usually make calls, and then enter the command “2201#”. Calling on this request, the user will receive a message with the connected service. Additional settings are available in the person’s personal cabinet in the “Blacklist” section.

  • After entering it, wait for a message to come with the activated service;

The second one is necessary for the parents of a child. It is free, but allows only to put a block on outgoing calls. The cost of the current personal one can be found on the official site;
  • It is better to use the personal control, so we choose it.

Now the user can personally block contacts. Through the personal cabinet you can set up this function in more detail. It is done in the “Blacklist” section. It also contains all the instructions.

Caller ID on Android

The main problem with the blocking of unknown numbers is that you can not call someone whose number is not in the list of contacts. This greatly complicates communication with couriers who constantly call from different numbers, cab drivers, who often do not come to the place they were called, government agencies, etc.Д. So if you often order something, blocking is clearly not your solution. But the caller ID is yours.

Caller ID requires the replacement of the voice assistant

Only after that can you turn on caller ID

But since the service has been around for a long time, you can be absolutely relaxed about the breadth of phone numbers.
