Why can't I send a text message when my mobile phone has a phone bill?

Hehe, in the system analysis, ..........

1 mobile phone has a phone bill, but it can't make a call and send a message, which means that the phone bill in the mobile phone is not enough to deduct the monthly rent, and it also needs to be recharged before it can be used

2. Point-to-point SMS function.

I accidentally canceled the peer-to-peer SMS service last time, which made it impossible to send and receive SMS. You can call 186 human customer service first and ask them to refresh the SMS function of your card again.

3 SIM card is damaged.

you can go to the business hall to test the SIM card. If the SIM card is damaged and its own function is wrong, you can change the card. You can change the card for 1 yuan without changing the number.

4. SMS settings.

enter the SMS settings, there is a center number, and see if your center number is the same as other people there. If it is different, change it to the same as them. If you don't have a center number, but you can accept it as you said, but you can't send it, you can ask your customer service.

The best way is to manually use 186. They will tell you what to do in detail, hehe.

I hope the above answers can help you.
