How to turn off China Unicom data plan and send text messages?

If you are canceling the traffic package of your number, this also depends on the traffic package you have activated. For example, if a China Unicom 2G user subscribes to a 3G intra-provincial data package, you can send the text message "QXLL" to 10010 to apply for unsubscription. If the unsubscription is successful, it will take effect the following month. If you are a China Unicom 3G user who has opened a 3G domestic traffic package, you can send the text message "QX3GLL" to 10010 to apply for unsubscription. If the unsubscription is successful, it will take effect the following month. If the number is subscribed to other traffic packages, it is recommended that you call 10010 to learn how to cancel.
