Xiaomi 1s youth edition can't receive SMS after changing the calling card! What's going on here?

I suggest you check the following steps to find out the reason:

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

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

I suggest you try to see if other cards plugged into Xiaomi's mobile phone can be used normally.

If it still can't be solved, please back up the data and enter the recovery to clear the cache, user data and all data. After entering the system, the data will not be recovered temporarily, and try to send SMS directly.

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