Iphone5 sends text messages with Unicom card, but it can't be received.

You can't receive short messages for the following reasons:

1. You can 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 none of the above problems exist, it may be related to the network function. Please call 100 10 customer service to handle this problem.
