Why doesn't Unicom mobile phone card display incoming calls and receive information?

This means that your mobile phone does not have caller ID service. You can directly call 100 10 customer service to apply for opening, or you can log in to Unicom's online business hall to open it.

As for the failure to receive SMS, it may also be caused by the failure to open SMS service. You can ask 100 10 to help you check the opening.
