Why can't yomi's mobile phone send a message if it has a phone bill?

1 The phone charges, but I can't make a call and send a message. It is because the phone bill in the mobile phone is not enough to deduct the monthly rent, and it needs to be recharged.

2. Point-to-point SMS function.

Last time, I accidentally canceled the point-to-point SMS service, which made it impossible to send and receive SMS. You can call 10086 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, there is something wrong with its function. Just change the card, and pay 10 yuan to change the card 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 others there. If not, change it to be the same as them. If you don't have a center number, but you say you can accept it, but you can't send it, you can ask your customer service.

The best way is to use 10086 manually. They will tell you how to do it in detail, hehe.

I hope the above answers can help you.
