What's wrong with sending text messages on mobile phones that others can't receive?

First of all, you have to see if your number has SMS function. If not, you need to turn on the SMS function first, and it can be used normally. If the SMS function is normal, but it cannot be sent, it is generally divided into the following situations:

1. See if there is only one person who can't hear from you. If only one person can't hear from you, it may be the other person's mobile phone.

2. If everyone can't receive the SMS, you need to reset the SMS center number (86 130 10969500+).

3. If the SMS center number is set correctly, it still cannot be used normally. I suggest you call 100 10 and ask the customer service representative to reinstall the SMS function for you.

4. If the SMS function can't work properly, then change the machine and card to test it.

5. If the effect is not good, then call customer service to hand over the problem to Unicom!
