Unicom 3g traffic package, what message should I send?

Sending "LJKT3GLL20" is the Unicom 20 yuan 3G domestic traffic package that takes effect immediately. After the traffic package is opened, it will not be cancelled, and it will be automatically renewed every month. If you need to cancel the editable short message "QX3GLL", just dial 10 10. Note: If Unicom mobile phone users in Tianjin need to cancel before 20: 00 pm on the last day of the month, whether there is a time limit for Unicom users in other provinces to cancel this service depends on local conditions.
