Why can't OPPOr9 send and receive text messages?

The mobile phone cannot send and receive short messages. Please refer to the following methods to try to solve this problem:

1, check the balance of the mobile phone to see if it is overdue. If you owe money, please recharge it.

2. Check "SMS" and "SMS Settings"-"in the mobile phone; Whether the information center number of "Information Center Number Settings" is correct (compare it with similar local cards or consult the operator to confirm the message center number).

3. Restore the backup data to the factory settings (Settings->; More-> Restore factory settings).

If the above methods cannot be solved, please take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and handling.

The reasons that lead to the failure of sending and receiving short messages by mobile phones are generally the wrong number in the information center, the number arrears, the abnormal reception and forwarding of network base stations, and the failure of mobile phones.
