Can I still use SMS to check the phone bill when the telecom card is down?

Generally speaking, it is unlikely. After the arrears, the telecom company will stop all functions of the mobile phone card. If the mobile phone has a phone bill, you can also use the arrears to call and send messages within a certain fee.

The method of inquiring telephone charges by telecommunication card:

1, call telecom customer service 10000, and inquire according to the voice prompts;

2. Edit the short message "10 1" and send it to 10000 to check the real-time phone bill;

3. Log in to the online business hall of China Telecom and select "Real-time phone bill inquiry";

4. Go to the local business hall to inquire.

If you owe money, general method 2 cannot be used.
