Why can't China Mobile receive Unicom's short message?

You can't receive SMS or verification code due to the following reasons:

1. Confirm whether the number of Unicom's SMS center is correct (contact local customer service for consultation in different places, taking Ningxia as an example: SMS center number+8613010796500);

2. Check whether the receiver's mailbox is full, delete it, turn it off and try again;

3. If it is still not received after deletion, you can change the machine or change the card for testing;

4. After eliminating the above reasons, you can contact the local customer service for inquiry and handling.
