In the afternoon, Xiaomi's mobile phone received a SMS reminder.

1 It is recommended that you click SMS-Menu-Settings-Advanced Settings-SMS Center Number to reset.

I suggest you try to call your friend to see if you owe money.

I suggest you try whether other cards can be used normally when plugged into Xiaomi's mobile phone.

If it still can't be solved, please back up the data, enter recovery to clear the cache, user data and all data, and try to send SMS directly after entering the system without recovering the data.

If it still can't be solved, it is recommended to back up the data and try the latest development version.
