One plus mobile phone can't send text messages

If your mobile phone can't send SMS, you can try the following methods to troubleshoot:

1, check whether the mobile phone is in arrears;

2, check whether the environmental signal is good;

The unstable signal in some areas may lead to the problem of sending short messages. It is suggested to try to change the location.

3. Please check whether the number of the SMS center is set normally (mobile Unicom only) and set the path:

Open the message → 3 o'clock in the upper right corner → Settings → Advanced Settings → SMS center number (please consult the operator for the specific number) and confirm whether the SMS center number is correct. SMS center numbers vary by operator and region. It is recommended to consult the operator to find out the exact number change and then try to send a message.

4. Consult the operator to check whether the SMS function is normal;

5, long press the SMS icon, click on the application information → application permissions, and check whether the SMS permissions are turned on;

6. Whether the 6.SIM card can be used normally in other mobile phones;

7. If the service number starting with 106 cannot be sent, please contact the manual customer service directly.

If the problem still exists after trying the above methods, I suggest you apply for after-sales service, and the network engineer will detect and handle it for you.
