I've been searching these forums all day at work (whoops) and have yet to find a definitive answer: I'm looking to buy a Galaxy S4 and would like to purchase it through Metro PCS in NYC (it's $10/mo cheaper than T-mobile). However, if the service sucks, then can I do BYOD with T-mobile? (i.e. take the same S4 and sign up with T-mobile). Is this possible or is there something I'm missing? Thanks a lot!
