Unicom Huawei p6 Zha lose SMS center number

When setting the number of SMS center, the operation mode of inputting "+"is different according to different mobile phone models, so you can refer to the mobile phone manual for operation. Some mobile phones have "+"on the "*" key or "#" key, and some mobile phones will have "+"if they press the "1" key or the "0" key for a long time.

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.
