Samsung mobile phone display can't send text messages or delete them.

Based on your feedback, I suggest you take the following steps to eliminate network and system problems:

1. Turn off the phone and restart it.

2. Check whether the number of the SMS center is correct. Operation: Information-Menu-Settings-SMS Center, and set the number of SMS Center. Because the center number will be different in different regions, it is recommended that you contact the network operator for confirmation.

3. Please try after uninstalling the third-party software installed on the machine.

4. Wipe the contact point between the mobile phone card and the mobile phone (whether the sim card is in poor contact), or try to replace the sim card (whether the SIM card is aging or damaged).

5. Back up mobile phone data (such as contacts, photos, etc.). ) and restore the phone to factory settings (Settings-Privacy/Reset/Private-Restore Factory Settings).

If the problem still exists, please bring the purchase invoice, maintenance card and machine to Samsung Service Center, and the engineer will check the machine. You can view the information of Samsung Service Center through the following link:.
