What short message should I send when inquiring about the phone bill package?

Hello, if you are the number of Beijing Mobile, you can edit the short message "CXYL" to 10086, and you can query the remaining information of various voice, short message and GPRS. You can also edit the short message "CXTC" and send it to 10086 to inquire about the voice package, short message package, mobile data stream package and group package that this machine will handle next month. Thank you for your support to China Mobile, and wish you a happy life!
