My dual-card mobile phone can receive short messages, but Unicom card can't send and receive short messages. How to solve it?

The processing method that the mobile phone cannot send short messages is as follows:

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.

5. Bring the mobile phone card to the local business hall for testing or replacement.

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

1, you can check whether the mailbox is full first. If it is full, please delete some information.

2. If you still can't get it after deleting it, 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 the above problems do not exist, it is suggested that you can contact local manual customer service to handle this problem.
