Hello, why can my mobile phone send MMS messages but not text messages? There is no problem with the SMS center.

Failures to send and receive text messages are generally caused by incorrect information center numbers, overdue numbers, abnormal reception and forwarding of network base stations, mobile phone malfunctions, etc. You can refer to the following methods to try to see if the problem is solved:

1. Consult the balance of the mobile phone card to see if it is in arrears;

2. Correct the information center number, first check the inside of the mobile phone Is the information center number in "SMS - SMS Settings - Information Center Number Settings" correct (compare with similar local cards or consult the operator to confirm the message center number);

3. Replace the SIM card or replace it with a different one Comparative observation of the time period;

4. Try restoring the backup data to factory settings (Settings--System "More"--Restore factory settings, do not check "Complete Clear");

If none of the above methods solve your problem, please bring your purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for inspection and processing.
