What if Xiaomi's mobile phone can't send text messages?

Mobile phones can't send text messages. I suggest you check the following steps to find out the reason.

Reset SMS center number

I suggest you click SMS-Menu-Settings-Advanced Settings-SMS Center Number to reset.

Call to check if there is any debt.

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

Try inserting another card into the phone.

I suggest you try whether other cards can be used normally on Xiaomi mobile phone.

Clear cache and user data

If it still can't be solved, please back up the data and enter recovery to clear the cache, user data and all data. After entering the system, don't recover the data for the time being, and try to send SMS directly.

Brush the line to the latest development version

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