Why can’t oppok5 send text messages?

If you are using an OPPO mobile phone (ColorOS system) and cannot send text messages, don’t worry, you can check it like this:

1. Confirm whether the mobile phone card is in arrears , to ensure that the phone bill balance is sufficient.

2. If "Sent" and "Delivered" are displayed below the sent text message, it may be a problem with the other party's mobile phone or network. You can turn on the "Get Delivery Report" function in "Information>Three dots in the upper right corner>Settings>Advanced Settings".

3. If "Sending Failed" is displayed below the sent text message or the status of the text message cannot be known, it is recommended that you check whether the mobile phone information center number is correct and set the path "Open SMS gt; three dots in the upper right corner gt; Settings>Advanced settings>Message center number", the SMS center number is different for each operator and each region. It is recommended to consult the operator to learn the exact number change and try to send the message again.

If the center number is incorrect, you need to correct it in the text message settings of your mobile phone, then restart or switch flight mode on and off to search the network again to see if it can return to normal.

4. If the center number is correct but you still cannot send text messages, restart your phone or switch airplane mode on and off to search the network again and try again.

5. It is recommended that you check whether the receiving number is correct and whether it contains special symbols.

6. If this happens in certain places, it may be related to the signal or network environment. It is recommended that you use it in a place with good signal.

7. If this happens when used in all places, it is recommended to replace the SIM card and compare it at different time periods. If it is determined that the problem is with the SIM card, it is recommended that you contact the operator; if the problem is with the mobile phone, it is recommended that you go to the OPPO official service center for testing.
