Mobile phone (Huawei P9) can't send short messages, but can receive short messages. How to solve it?

1. If it is a dual-card mobile phone, card 1 can move card 2 to telecom, but card 2 cannot send short messages. It may be because the card 1 has turned on the VoLTE function, and there is a network conflict. I suggest you turn off the VoLTE function of 1 card and try again.

2. If you choose to send a short message, and the prompt fails, you can choose

① Enter SMS > More > Settings and select Restore Default Settings;

② Go to Settings > Application Management > More (or Menu) > Display System Flow, then select information, click Save, and then select Delete Data to clear the cache;

③ Go to Settings > Advanced Settings > Backup Reset > Restore Network Settings (some models don't need this setting), and then try whether you can send SMS;

3. If the above can't restore the SMS sending function, please back up the important data and restore the factory settings to try to solve it. If it still can't be solved, please back up the important data in advance and take the purchase invoice to Huawei customer service center for testing and processing.
