Where to set the short message gateway exception?

The method is as follows:

First: power on and off and restart. It seems simple and has no technical content, but under normal circumstances, restarting the phone can indeed solve many problems. I believe this is the first step for many friends when they encounter problems.

Second: Check the SMS center number settings. The SMS center number is +8613800100500. Check whether your SMS center number is correct.

Third: Check for abnormal processes and viruses. Some firewall-type software will block the normal sending and receiving of text messages. In this case, you need to manually set the corresponding options. If you suspect that there is an abnormal process or virus causing the problem, it is recommended to use mobile anti-virus software to check and kill it.

Fourth: Restore factory settings. When mobile phones frequently malfunction, this may be the last resort. Restoring factory settings, that is, master clear or master reset, only takes a few minutes to solve terminal-related problems. It is recommended to use Directory Manager to back up your address book before restoring to factory settings.
