Is the mobile campus card of Yantai University easy to use?

Personally, I think it's very useful. At school, you have to pull the internet cable yourself (especially those who like to play games like this). Generally, freshmen are in South School. One kind of network cable that South School can pull is the school campus network, which has a relatively slow network speed, and the other is mobile broadband. It is said that this year, the network speed has been upgraded to 100 megabit, and the network speed should be faster. Generally, a mobile campus card will send mobile broadband for free, but the mobile card is very affordable and has a large traffic. It will not become 3G for no reason like Unicom, and the network speed will soon solve the trouble that I don't have a network when I scan the code to pay in the school cafeteria. For example, our dormitory has a mobile campus card, and it is free for us to use the campus card for phone calls, and it doesn't cost anything. And I remember that when I first started school, the preferential treatment was particularly strong. Charge 100 yuan to send 244 for one semester is basically no problem. Every month I will have the remaining traffic from last month, and it will automatically transfer the remaining traffic from last month to this month.
