What should I do if my Samsung phone cannot send text messages?

If the mobile phone cannot send short messages, it is recommended to:

1. Check whether the mobile phone bill is sufficient.

2. Check whether the information center number is entered correctly: Information-Menu Key-Settings-SMS Settings-Information Center-Set Information Center Number (Please contact the local network operator for the information center number. Telecom cards do not have it. Information center number settings).

3. Try changing other SIM cards.

4. Check whether the machine has firmware/system update push notifications. If so, please upgrade the phone to the latest version.

5. If it doesn’t work, please back up the data in your phone (contacts, multimedia files, etc.) and restore the machine to factory settings. (Note: Back up relevant data before updating the version or restoring to factory settings to avoid affecting use)
