Verizon did it, Sprint did it, and Cingular did it, now T-Mobile has too: raised the per-message cost of SMS messages. I guess they were just feeling left out. I'm still bothered by the fact that as the infrastructure costs of this data goes does that the price is going up, but oh well. I recently switched to an unlimited text plan, so I'm not sure I'll be able to use this technical breach of contract to break my contract, but if you're itching to leave T-Mo, here's your chance.
As has been the case when other carriers have made similar moves, this constitutes a material breach of contract on T-Mobile's part, allowing customers to jump ship without paying the hefty $200-per line ETF
