Why can't oppo r7 send short messages?

Hello, the reasons and solutions for the failure of sending and receiving short messages:

Causes: wrong number of information center, number arrears, abnormal sending and receiving 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. Consult the mobile phone card to exclude the phone bill balance.

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.
