Your math isn't correct. If one switches to T-Mobile in the US, you get pretty substantive savings. The con is that you don't get a phone subsidy. I did the math a while ago. Don't know how it holds up. As a datapoint, we pay between $90-$100 for two phone lines with T-mobile. Includes 500MB data/tethering per phone, unlimited minutes in the US and text messages.
