China Telecom's traffic inquiry SMS, what number should I send to China Telecom's traffic inquiry SMS?

users in dongguan, Guangdong, who send 73 to 11 or CXLL to 11, can find the quasi-real-time internet traffic of the current month (note: it is applicable to users who settle accounts by natural month (that is, post-paid users). If they are prepaid users, it may be possible to find out the monthly rent on the first day of each month, but it may not be accurate. It is not suitable for users who settle accounts by dynamic month at the middle or end of the month).
