What if oppoR9s can't send and receive text messages?

OppoR9s can't send and receive text messages. The failure to send short messages is generally caused by the wrong number of the information center, the arrears of the number, the abnormal reception and forwarding of the network base station, and the failure of the mobile phone.

You can refer to the following methods to see if you can solve it:

1, consult the phone bill balance of the mobile phone card to see if there is any arrears;

2. Correct the number of the information center. First, check whether the information center number in "SMS-SMS Settings-Information Center Number Settings" in the mobile phone is correct.
