Why can't my mobile phone suddenly receive SMS verification code and customer service SMS? What happened?

1. Please check whether the mailbox is full first. If it is full, please delete some information.

2. If it is still not received after deletion, you can change the machine or card to see if it is a hardware factor;

3. 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 situation has not been solved, it is recommended to contact the local manual customer service for handling.
