How does Unicom mobile phone return traffic through SMS?

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. I suggest you check it through the short message description in the online business hall: /oftenInfo.html? MenuId=0004000 10002, the commonly used short message description has been found. At the same time, you can also call the local hotline 100 10 to cancel the traffic package.
