OPPO mobile phone messages cannot be sent out

If only the message cannot be sent, but other functions are normal, then it is caused by the incorrect setting of the message center number of the mobile phone.

You can reset the information center number through the following methods:

1. Turn on the phone, find the "Settings" item on the phone desktop, and click to enter.

2. After entering the settings, go down the menu and find the "Information" column, and click to enter.

3. After entering the information, find the "Advanced" column and click to enter.

4. After entering the advanced settings, find the "Information Center Number" column and click to enter.

5. After entering the information center number, find the SIM card to which you cannot send text messages and click to enter.

6. After entering the information center number, fill in the correct operator information center number (you can call the operator's customer service number for consultation, the number is different in each location), and save it.
