1. The mailbox is full. It is suggested to delete some information.

2. Due to hardware factors, it is recommended to change the machine or card for testing;

3. The weak signal affects the short message reception, so it is recommended to go to other places for testing.

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.
