Why is the phone always on and the phone just can't get in?

If the number is used normally, you can make a normal call but can't answer it normally (including beep). The following situations are not excluded:

1, the mobile phone has a number interception function, which intercepts normal incoming calls by mistake. It is recommended to check the mobile phone;

2. If the mobile phone or mobile phone card fails, it is recommended to replace the machine card for testing;

2. Wrong number. The call was transferred to another number. It is recommended to cancel call forwarding or reset.

3. The local signal is unstable and there is a problem of calling out. It is recommended to try again in another location.

If the above reasons are not solved, it is suggested that you can contact the local Unicom customer service for handling.
