My secret mobile phone is Unicom. I don't know why, when I send a text message to change my password, it always shows that sending failed, and it is saved in the outbox. It wasn't like this before.

Can't you just change your password and send text messages or can't you send all text messages? If it is the former, check whether there is a limited SMS port in mobile phone settings or security software, and the latter can try to reset the SMS center number, which can be obtained by consulting the hotline 100 10.
