Why can't Huawei p7 Mobile Version 4 use Unicom card to receive SMS?

If you can't receive SMS, I suggest you check it in the following ways:

1, I suggest you change your mobile phone and see if you can send and receive short messages;

2. If you can send and receive short messages, I suggest you plug the card back into your mobile phone and send yourself a short message to see if you can receive it.

3. If not, I suggest you check whether it is a sim card problem;

4. Check whether the number of SMS center is set correctly.

If you still can't solve your problem, I suggest you take your mobile phone card to the local business hall for testing.
