How to send SMS back to Unicom's monthly traffic?

According to the different flow treasures you handle, the cancellation methods are different. For example, if you are a 3G user of Unicom and have a 3G domestic traffic package, you can send "QX3GLL" to 100 10, and the product will expire on 1 the following month. If you are a 2G user and have launched a 3G provincial traffic package, you can send QXLL to 100 10 to unsubscribe from the 3G provincial traffic package. The product will expire on 1 next month, and the Internet access function of 3G mobile phone will be turned off. At the same time, you can also call the home hotline 100 10 to cancel the traffic package.
