I received a text message saying that I have used 40G this month. I think it's free traffic. I have used 33G daily rental treasure and 6G daily rental treasure. Do I still have free traffic?

Take Unicom Tencent Dawang Card as an example:

According to the principle of fair use of the network, when the total traffic (including the exclusive traffic using Tencent software) reaches 40GB in the current month, the internet access function will be turned off and it will be automatically restored in the next month. If you want to continue to use it, you can handle the "unsealing service" through China Unicom's online business hall, China Unicom's mobile phone business hall and SMS business hall. After dissolution, all traffic exceeding 40GB (including Tencent Software's exclusive traffic) will be charged directly according to the daily domestic traffic rent 1 RMB 800MB/ day, and the traffic will not be effectively carried forward on the same day, so it will be charged according to the volume, and there will be no charge for unused traffic.
