How to install a default SIM card

On the default panel for calls, we install the SIM card that will be constantly used for calls. This is or

If you mark the 3rd cell, then with each call of the subscriber, Redmi will ask you which SIM card you want to use to call in each individual case-with which SIM card do you want to call now.

Methods of activation of SIM cards

In the case of smartphones in which the global version is installed, the error that arises can be eliminated by activation of SIM. It is necessary that Mi Account begin to recognize the phone number. You can achieve in the following ways:

  • Enter the number manually in the format in which the Mi Account system will be able to determine it;
  • Activate the phone on the Xiaomi website;
  • call the operator to allow him to send messages abroad.

These methods will help to eliminate the problem that has arisen. Each of them should be said separately.


If the probable reason lies in the fact that the phone number on Xiaomi was introduced incorrectly, then in this case a very simple way can help. It is necessary to click on the notification “SIM card is not activated”. Pressing involves sending a request to the Xiaomi database to confirm the registration of the number. Since it is indicated incorrectly, a mistake will be displayed that the message could not be sent. Here you will need to press the repetition key. This action will have to repeat about 4-5 times so that Mi Account suggests changing the SIM card number to another. After that, it remains only to enter your number in a different way (remove the code “7” or, conversely, add it).

Activation on the site

The method is very common among users. It implies the entry of numbers not through a mobile device, but by using the computer version of the MI account. It contains more capabilities by default, the most common among users and, in this regard, is served much more stable and does not cause failures. In order to enter the computer version of the account, you need to follow the link: https: // Account.Xiaomi.COM/Static/Res/C9e52D8/Account-STatic/HTML/LOGIN/DIST/V2/SGP/Login-ROU_.HTML. When the page opens, it will become necessary to enter data for the entrance. After that, the window will open, in which you need to select the “Safety” item, then open the “Phone for Restoration” subsection and enter the phone number in it.

Upon completion of the described actions, an SMS with code will be received on a mobile phone. When it is introduced in the corresponding window, the account is activated and the message will disappear.

Note: The procedure should end with a reboot of the smartphone, otherwise the message will continue to hang in the notification line.

Through the SIM card operator

Removing the lock can be made by calling the telecom operator that provides telephony services. Here the problem is solved by the fact that the operator removes the restriction on sending messages to foreign numbers. Indeed, with such a ban, the SIM card cannot send an SMS with confirmation of activation in the Mi Account system. After lifting the ban, SIM automatically directs confirmation to the Mi Account program, then the number is successfully entered into the database, the user is identified, and the error disappears from the notification panel. However, restart the device still does not hurt.

If the problem has appeared after updating on

If the SIM card stopped working immediately after you updated the smartphone to the new version of the OS, probably the problem is precisely in the firmware. This is especially true if the developers have only recently released a software update (as a rule, within the first 7–9 days after the announcement of the new version, the developers correct bugs). It is also possible that as a result of the update there was any error, and the new in terms were incorrectly established.
