I can’t send text messages on my mobile phone. I can receive text messages from other devices. But I can’t send them even if I use another phone. What’s going on?

From the perspective of the phenomenon, it is a card problem. If the text message cannot be sent even if you change the mobile phone, the most likely reasons are:

1. There is a problem with the text message center number setting. You can check it in the text message settings of the mobile phone. If you don't know, you can ask 10086;

2. The SMS sending function is turned off, please contact 10086 to confirm!
