Why can't OPPO receive SMS?

Reasons and solutions for the failure of sending and receiving short messages: Reasons: wrong number in information center, number arrears, abnormal receiving and forwarding of network base station, and mobile phone failure. Solution: 1 Correct the information center number. First, check whether the information center number of "SMS-SMS Settings-Information Center Number Settings" in the mobile phone is correct (compare it with similar local cards or consult the operator to confirm the information center number); 2. Information centers are stored in mobile phone cards. You can change a mobile phone card and restore the factory settings (Settings-System "More"-Restore the factory settings, please do not check "Clear completely") to eliminate the contrast; Determine whether it is a mobile phone card problem or a mobile phone problem; 3. Change the observation and comparison in different time periods; 4. Exclude the phone bill balance of the consulting mobile phone card; If the above methods fail to solve your problem, please take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and handling.
