How to query the remaining call duration and traffic of the package through SMS?

I don't know what card you are using. The sending code of each province is different. The best way is to call the manual service number:

1, Unicom sends a text message to 100 10 to check the balance of the package.

2. Telecom sends the short message "108" to 1000 1.

3. Send CXBX to 10086 to check the remaining number of SMS messages in the current month, and CXGTC to check the remaining flow of GPRS packages in the current month.
