The Unicom 3G traffic package I handled was not processed when I cancelled it by SMS.

In this case, there may be an error in the instruction you sent. I suggest you check the status of the opened traffic package in the online business hall www.11.com first. If it has been opened, you can unsubscribe directly in the online business hall. Specific path: You can log in to the online business hall/homepage and click Self-service > Do business > Package handling? > 3G traffic packets are being processed.

For example, if you apply for a 3G provincial traffic package, the traffic package you have ordered will be displayed on the page, and then you can click unsubscribe directly. If the status is not ordered, it is recommended that you call the local 11 to check.
