A reward for high marks, the problem of mobile phone cards.

Ha ha laugh ... your question seems complicated, but it's actually very simple. Is how to meet your requirements with the least amount of money. Let's just say that I think this is the cheapest. Let's start with a M-Zone MO package for one month 16. Its business includes 100 megabytes of traffic in the province (you can install a Fetion software and add the other party as friends, so how many messages you send are free, and the 100 traffic you send is absolutely inexhaustible, and the rest can be used to browse the web, download wallpaper and listen to songs) and 120 short messages in the network. But making a phone call is a bit expensive. Then you tell the truth at night, it's super affordable, and there's nothing to talk about ... Hehe, so you have to deduct 16+6=22 yuan for one month. Plus your phone call, the total cost is estimated to be around 50! ! ! ! ! Affordable! ! !

Is my answer detailed enough? Adoption ... hey hey. ...
