3g card Unicom, Motorola's mobile phone, always fails to send text messages, and it also fails to change mobile phones. What happened? The card problem?

The short message center number of Hebei Unicom number is+8613010180500.

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.
