How does China Unicom send short messages to return traffic?

Hello, there are different cancellation methods according to the different flow treasures you handle. 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 mobile phone number and service password to log in to Unicom's online business hall www. 100 10.com to cancel the traffic package.
