Help, Xiaomi's cell phone keeps texting.

Please set the following SMS center number without any arrears and try again.

If it is not resolved, please check whether the following reasons exist:

1. Put the mobile phone card into other mobile phones to check whether you can send and receive short messages. If you still can't get it, it may be that the phone is in arrears or the SIM card is broken, so you need to pay the fee or apply for a new SIM card in the local business hall.

2. If you can receive it, plug the card back into your mobile phone and temporarily uninstall your system security software, because it may be caused by the automatic interception function.

3. If it is still unresolved, please back up the data first, enter the recovery mode to clear the cache, user data and all data, and do not restore the system settings after entering the system.
