I work at T-Mobile, but have AT&T service on my iPhone 5. I could get my own employee plan at T-Mobile and save some money. T-Mobile service isn't as good as AT&T where I live, but it's not bad by any means. I definitely plan on staying with the company for at least 2-3 years but after I finish school unless I can get a good job related to my degree I don't plan on staying there forever. Switching to my own line at t-mobile would save me around 44.50 a month. I'm under contract with AT&T still but my ETF is currently around 125-150 if I remember correctly.
The other issue is devices. My iPhone 5 on AT&T doesn't have all the frequencies T-Mobile uses to get the best service. I do have a T-Mobile Galaxy S III lying around I can use so I don't have to buy another phone (I realize devices are largely personal preference). I could at least sell the iPhone for a pretty bit of coin.
You guys helped me make the right decision with the recent job offer I had come up, I'm looking for your opinions on this now to also guide me in the right direction.
Save money, IMO.
