Ahh, T-Mobile US. T-Mobile is a big, multi-national corporation. They're world-wide, just like the dollar.

IMO it is pathetic a corporation is able to charge more based on type of device used instead of more reasonable factors such as data usage. Has anyone tried to sue T-Mobile US for this?

Reminds me of @Home here. They didn't allow one to use NAT. Customer would need to pay more then. Although they'd also get another IPv4 for the next machine. Bullocks of course. @Home should instead keep data usage into account. But then they cannot advertise with only the speed and FUP...
