The phone can't make a call, which means the phone is not connected. What happened?

Causes and solutions of abnormal telephone calls;

1. Check whether the phone is set with functions such as call forwarding, enabling airplane mode and call barring. It is recommended to cancel and try again.

Second, the number is down, which affects the call. You can check the number information to know the status of the number. If it is not normal, you need to restore the normal state of the number before you can answer the phone.

Please check whether the mobile phone is in arrears. If it has been charged, you can check the charging status.

4. Please check whether the mobile phone card is damaged or not inserted correctly. You can go to the local business hall for testing or changing your mobile phone card.

5. It is suggested that you can restart or switch flight modes and try again. If you still can't answer the phone normally, you can also change your mobile phone for testing.

If this is not the case, you can contact local manual customer service and give feedback.
