Refueling package refers to the flow refueling package, which is the flow package provided by operators to customers. When the mobile data traffic of the mobile phone runs out, you can open the traffic refueling package without worrying about the high traffic cost. The refueling package can be superimposed on the original flow package, and the refueling packages are not mutually exclusive and can be freely combined.

The education refueling package was opened that month and will be cancelled automatically next month. You don't need to unsubscribe, you can reopen it when there is no traffic.
