Why can't I get any messages on my card at 100 10?

According to the information you provided, it is not ruled out that you can't receive the relevant information of Unicom because your mobile phone is set with a blocked Unicom number. It is recommended that you try to restore the factory settings or replace other mobile phones for testing.

The above situation remains unresolved. It is recommended to contact the Unicom customer service to which the number belongs.
