Talk7x updates miui, and you can't send text messages.

Mobile phone can't send text messages. 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 whether other cards inserted in Xiaomi's mobile phone can be used normally.

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

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