I'm on T-Mobile, with about 10 lines (business plan)
But I fail to see why anyone is still on AT&T.
With T-Mobile being the cheaper option, and Verizon having a vastly better network than AT&T while still being cheaper, it astounds me that people are still on AT&T.
This is not meant as a personal attack, please explain why you wouldn't switch from them?
I switched to AT&T from Verizon so I could buy the original iPhone. WiFi is everywhere where I live so I rarely use over 2 GB of data. My bill is less than $60 per month including taxes and fees. I stay because I've not found a cheaper plan with a carrier that has better coverage. I need a plan with LTE coverage outside of the most populated areas of the state which is why I haven't switched to T Mobile. The Verizon plans I've seen aren't cheaper either. I couldn't care less about faux "unlimited" data plans. I want the best coverage at the lowest cost for the amount of data I use.
