I was on T-Mobile for 6 months when the company I worked for made it the only choice. about a thousand years ago and it was misery compounded with a large order of F-You. They didn't care about any service issues.
I've been with AT and T the vast majority of my cell time (not jail cell
UncleWede and
shoei 
) beginning with Cellular One. My current AT and T contract goes back almost 18 years. I have 3 Biz phones on it and 5 personal phones. I wouldn't go to anyone else.
