I accidentally turned off the SMS function of my new mobile phone. How can I open it?

If the mobile phone can't send short messages, Samsung mobile phones generally suggest the following steps for troubleshooting and handling:

See if you can answer the phone. If not, please check whether the machine signal is stable and whether the phone bill is sufficient.

If the phone call is normal, but you can't send SMS, the suggestions are as follows:

1. Check whether the information center number is correct (please contact the local network operator for the information center number, and the telecom card has no information center number setting).

2. Try to replace another SIM card.

3. Check whether the machine has a firmware/system update push notification. If yes, please upgrade your phone to the latest version.

4. If it is invalid, please back up data (contacts, multimedia files, etc.). ) and restore the machine to factory settings.

If the problem still exists after the above operation, please take the purchase invoice, maintenance card and machine to the service center for inspection.
