I have stayed with AT&T.

1) Main reason, they are cheaper for what I need.

2) But, also, I have never had an issue with them save the first year (when they were Cingular) and they had a horrid website. Which they fixed after that first year (but it was annoying enough I was thinking of shopping around when my contract was up so if they hadn't fixed it I might have changed to T-Mobile as Verizon back then was still too expensive and Sprint is just right out).

3) Also, I like that they are very good about grandfathering plans. Sure on my unlimited when they added "features" they didn't allow the unlimited plan to use it but they didn't make me lose anything I didn't already have either so no biggy there. They easily could have said that on the new iPhone they didn't offer an unlimited LTE plan and the unlimited plan I had was a 3G plan so it wasn't available for the iphone but they didn't. People keep focusing on the negative, but I think that was pretty cool of them. Beats having to buy my iphone in full if i want to keep unlimited with absolutely no guarantee they won't just discontinue the unlimited plan entirely.

4). I like how I can change plans from month to month depending on what I'll need. Not that I take advantage of this anymore since almost everything on my plan is grandfathered, it fits what i need, and I don't want to lose my grandfathered plans. Between me and my roommate we both get unlimited data and all the minutes we can use (seriously, we accumulate rollover minutes) for around 50 bux each (and that includes tax).

I think if I were to change it would be to go to one of those small companies that do pre pay plans cause I hear you can get way better deals that way (some one was telling me for 30 dollars he gets unlimited data and 100 minutes and really I don't need much talk time). Verizon is way too expensive and even T-Mobile can't beat the price that guy was telling me. Plus if I found a better deal I could just change the next month.
