My phone can’t send text messages, but I can receive them. What’s going on?

Hello,

1. Please put the mobile phone card into another mobile phone to check whether you can send and receive text messages.

2. If you cannot receive text messages, please contact your network operator to see if there is a problem with the SIM card.

3. If you can send and receive text messages, it is recommended that you reinsert the card into your phone and send yourself a text message to see if you can receive it.

4. Please enter the SMS center and contact your mobile operator to check your SMS center number

5. If the number is correct, please temporarily uninstall your system security software

6. If the problem still persists, please back up your data, enter recovery to clear cache, user data and all data, and do not restore system settings after entering the system

I hope the above reply is helpful to you. help.
