Here it goes... I've been a loyal T-Mobile customer for 5 years, every call I have had to them is quick courteous and resolved... Also I understand that if I went over my minutes I did, contract whatever all carriers do that, my main issue is about sim cards and the quality of phones T-Mobile sells. I've had 6 sidekicks replaced by Asurion each one refurbished each one with an issue, screen blank buttons not working, ball not rolling, the problem with sim cards obviously is that possibility of stealing a phone and slapping a sim in and your good to go which in turns raises the insurance deductible... To a sick $110, Asurion also provide claims for sprint and other carriers, which carry a deductible of $50 no matter what phone it is, also T-Mobile does not have warranty or repair centers if you have any issues with a phone, they have to send a you new one and it has to be under the warranty period if not your stuck with a high deductible.
Also when I purchased 2 more lines. I was assured I wouldn't be charged for activation fee... and astounding $39.00 per line, so I called and of course there was no notes, luckily the rep I spoke with was compassionate and removed those for me to say the least.
