What if the mobile phone can't send text messages?

The failure of sending and receiving 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 conduct relevant investigations according to the following methods:

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

2. 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);

3. Compare and observe the changes of SIM card and different time periods;

4. Try to restore the factory settings of the backup data (Settings-Other Settings-Backup and Reset-Related Cleaning).

If the above methods fail to solve the problem, please take the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and handling.

You can check in the following two ways:

1, OPPO official website-service-service network query, related search.

2. Pay attention to the official account of "OPPO" WeChat on mobile phone WeChat. After entering, click Service Station-Nearby Service Point to inquire the specific address.
