After changing the mobile phone card, the network short message is not available, showing that it is currently offline, just change the card! Explain that the changed card can be connected to the Internet. Hi!

You tried to log out of Xiaomi account, and then log in again.

If it still doesn't work, it is recommended to try to back up, empty the data of the SMS and try again.

I suggest you try the following methods:

(1) Click Settings-Applications-All-Find Software-Clear Data, clear the software data and open it.

② After uninstalling, download and install the corresponding program again.

(3) If all the software is slow to open or there are problems in opening, you can back it up and try to clear the cache and user data when restoring. Methods: Press and hold the "Volume Increase Key" and then the "Power Key" when the power-on screen appears, and then let go to resume. Select simplified Chinese > clear data > clear cache+clear user data. Tip: The touch screen is temporarily disabled in the recovery state. Please confirm with the "Power Button" and select the "Volume Button".

(4) If the corresponding program has problems and other software programs are normal after the above operations, it can be judged that the program is incompatible with the system, and you can try to replace other versions of the program or game.

⑤ It is recommended that you back up your system version and try again.

A more detailed description of the problem will help netizens understand your troubles and help you solve the problem more accurately. Thank you for supporting Xiaomi mobile phone!
