What package does Unicom use to lift the speed limit?

Unicom can use "accelerated traffic package" to lift the speed limit. The user opens the China Unicom APP, clicks on the traffic area of the "Service" page, and selects the traffic package subscription he wants to apply for, then the speed limit can be lifted. In addition, users can wait for 0: 00 next month on 1 to automatically restore the normal network speed.
