Unicom Ali Bao Xiaoka can send text messages, but what should I do if I can't receive them?

Failure to receive SMS or verification code may be due to the following reasons: 1. Check whether the inbox is full, please delete some information and 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.

Tips: If the above problems do not exist, you can contact the customer service of the local operator to reflect.
