What if vivox9 can't send and receive text messages?

First, vivo mobile phones 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 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 problem does not exist, please contact the local manual customer service to handle this problem.

Second, the mobile phone can't send SMS processing method is as follows:

1. You can change your mobile phone to 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 there is a problem with the sim card;

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

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