I didn't know how to unsubscribe from the 20 yuan package, so I booked it myself.

It is recommended to enter the traffic packet ordering channel to see if there is a cancellation prompt.

For example, if you open the SMS, check whether there is a prompt to cancel the operation when the SMS reminder is successfully opened. If it is opened through the mobile phone business hall, you can also directly check whether it can be cancelled through the mobile phone business hall. You can also contact the local customer service directly to cancel.

If you have any questions about opening business, you can contact local customer service or local business hall for feedback.
