Why can't Samsung NoteGtn7oo receive the SMS from Unicom customer service?

You can't receive SMS or verification code due to the following reasons:

1. You still can't get it after deleting it. You can change the machine or card to see if it is a hardware factor.

2. After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

If the above problems do not exist, it may be related to the network function. Please contact the local manual customer service to handle this problem.
