There is something inhertly wrong with an unlimited plan that is not unlimited. It's not about what is enough and what's not enough for most customers, it is simply that in this cases some customers are beind decieved ( because they expected to recieve something they were offered), to remedy this issue is to just don't call it unlimited. No one is forcing them to offer unlimited plans!
Generally, you cannot walk into a restaurant and just eat for as many days as you want, even when they advertise unlimited buffet. There are expected limits to unlimited offerings, and considering the state of the mobile network, it's not that surprise.
The price one pays for pursuing any profession, or calling, is an intimate knowledge of its ugly side. -- James Baldwin
