Xiaomi can't send text messages to the Internet.

Xiaomi's mobile phone displays services, but can't surf the Internet, make phone calls, send text messages, etc. The reason for this is the following：

1) The mobile phone is in arrears. Please check whether the phone bill balance is in arrears.

2)Sim card problem, I suggest you don't try more cards or try to insert your multiple cards into other mobile phones.

3) Mobile phone system operation error. If it is not normal, it is recommended to close it and then open it again. Only factory settings are restored. If you restore the factory settings, it still doesn't work. Just send it for repair.
