China Unicom has launched an unlimited traffic package. Is this really "unlimited"?

In order to ensure the fair use of all users' networks, the ice cream card implements the following principles of fair use: domestic traffic provides 4G network speed in the first 40GB every month, and decreases to 3G network speed (up to 7.2Mbps) after exceeding 40GB. After cumulative use of 100GB, the data access function will be turned off, and it will be automatically restored the next month, and the speed limit function will be enabled after SMS notification; Before April 2065438+07 1, the traffic speed limit function will not be enabled temporarily.
