The issue i have with it all is everyone thinks tmobile is awesome and pro-consumer, when its the bottom line they care about just the same as the others. they shook up the industry and got a lot of subscribers by it, painted the underdog and for the every-man.
i signed up with a refurb xperia z, had monthly payments of 10 a month, was on their cheapest 50 dollar plan and was paying 80 bucks a month after taxes and fees etc. 80 is how much i was paying for a 2 year contract with sprint to have any device i wanted and unlimited lte. now they changed their plans so that if you want a note 3 with unlimited data you have to pay 80+30 for the plan and phone, add on taxes etc and it would be cheaper with att/verizon (granted you dont get unlimited but most people dont go over 3 gigs).
they changed how the jump plan works to cost even more money, at the end of the day the only thing they did that they wanted to was appear to be more valuable in a buyout offer, the parent company has been looking to get out of the US for years. now that the name tmobile actually means something it means they can get a good deal.
