Ali trumpet can send short messages, but can't receive any short messages. What happened?

You may not receive SMS or verification code for the following reasons:

1. Check whether the inbox is full. Please delete some information before the test.

2. It is recommended to change the card or the mobile phone for testing to check whether it is a mobile phone problem;

3. It is recommended to check whether the interception function of mobile assistant/incoming call/firewall is set to all short messages. If so, the reception of short messages will be affected. Please turn on your phone and try again after setting it correctly.

4. After eliminating the above reasons, you can also try to see if 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, you can contact the customer service of the local operator to reflect.
