Can't exchange traffic with my letter, saying that the mobile phone number is in an abnormal state.

1. According to the information you provided, if the status is abnormal when exchanging trust traffic, it is not excluded that it is caused by the following circumstances:

The number 1 is in an abnormal state such as arrears and downtime;

No.2 was blacklisted;

3 Real name registration information is incomplete.

2. If this is not the case, it is suggested that you can contact Unicom's manual customer service for verification. The actual situation is subject to local policies.
