What should I do if my OPPO mobile phone can't send short messages?

If you use an OPPO/ One Plus phone, if the phone can't send short messages, you can refer to the following steps for troubleshooting:

1. When you can't send SMS, you can't receive SMS and verification code:

(1) If this happens in some places, it may be related to the signal or network environment. I suggest you leave this area for a distance, restart your mobile phone or switch flight modes to see if you can solve the problem.

(2) If this happens everywhere, it is recommended to replace the SIM card and compare it in different time periods. If it is determined that it is a SIM card problem, it is recommended that you contact the operator for handling; If there is something wrong with your mobile phone, I suggest you go to the official service center of OPPO for testing.

2. When you can't send SMS, you can receive SMS and verification code normally:

(1) If the port number transfer service has just been handled, it is recommended to wait for the operator to open the SMS function before trying.

(2) I suggest you check whether the number of the mobile phone information center is correct (please consult the operator for confirmation). If the center number is incorrect, you need to correct it in the SMS settings, restart or switch the flight mode to search the network again to see if it can return to normal.

(3) I suggest you check whether the short message you sent contains sensitive characters or information.
