Why can't my Xiaomi mobile phone send text messages, and it keeps showing when it is being sent? What happened?

Please open Settings ~ Applications ~ Information ~ Clear Data and try to see if it works.

Still not working. Please put your mobile phone card in another mobile phone to see if you can send and receive short messages normally.

If you can't send and receive SMS normally, please contact the network operator to see if it's the sim card.

If the mobile phone can send and receive short messages, I suggest you re-insert the card into the mobile phone and send yourself a short message to see if you can receive it.

You enter the SMS center and contact your mobile operator to check your SMS center number.

If the number is correct, please temporarily uninstall your system security software.

Still can't solve it. Please back up the data, enter recovery to clear the cache, user data and all data, and do not restore the system settings after entering the system.

Still unable to recover, please check at the maintenance point near you.
