How can I cancel my subscription if I buy a Guoyou card?

There is no refund after purchasing the national excellent punch card.

After the successful customization of the traffic package, the user's money has been deducted, and the refund is not supported after the service takes effect. If you don't want to use it, you can unsubscribe by sending a short message to 10086, but the monthly traffic fee will not be refunded.
