Unicom's 8 yuan package fee of 4G.

Pre-storage of 50 yuan means that when opening an account on the new network, at least the telephone charges in 50 yuan need to be pre-stored. It doesn't mean that you have to pay 50 yuan a month and spend 8 yuan at least. It means that you only subscribe to 10 yuan's traffic package business, and the traffic package is 20% off. So 8 yuan/month, if you need to order other packages, you need to add fees to them.
