At present, Unicom has launched a package with traffic safety, and different packages have different speed limit rules. For example, Xiao Bing Shenka 99 yuan: the monthly fee is 99 yuan/month, and domestic traffic is free to use (that is, domestic traffic is free to use). The first 20GB provides 4G network speed every month, and then the network speed drops to the highest 1Mbps. If the monthly traffic exceeds 20G, the speed will be limited and the network speed will slow down.

Tips: Take Anhui Province as an example. There may be differences in policies among provinces and cities, and the attribution policy shall prevail!
