How to restore SMS function on OPPO mobile phone

If your phone cannot send text messages, don’t worry, you can check it like this!

1. If "Sent" and "Delivered" are displayed below the sent text message, it may be a problem with the other party's mobile phone or network. You can turn on the "Get Delivery Report" function in "Information>Three dots in the upper right corner>Settings".

2. If "Sending Failed" is displayed below the sent text message or the status of the text message cannot be known, it is recommended that you check whether the mobile phone message center number is correct (you can consult the operator to confirm the message center number). If the center number is incorrect, you need to correct it in the text message settings of your mobile phone, then restart or switch airplane mode on and off to search the network again to see if it can return to normal.

3. If the center number is correct but you still cannot send text messages, restart your phone or switch airplane mode on and off to search the network again and try again.

4. It is recommended that you check whether the receiving number is correct and whether it contains special symbols.

5. If this happens in certain places, it may be related to the signal or network environment. It is recommended that you use it in a place with good signal.

6. If this happens when used in all places, it is recommended to replace the SIM card and compare it at different time periods. If it is determined that the problem is with the SIM card, it is recommended that you contact the operator; if the problem is with the mobile phone, it is recommended that you go to the OPPO official service center for testing.
