I was going to dump AT&T and go with verizon until I asked around, a few were happy but anyone that had to deal with them for anything other than paying a bill was not happy, I am not sure about their coverage now, but a few years ago it wasn't the best, I would have no signal while standing in a major downtown city but nearly full signal in the mountains?? That would be fine if I was working in a cabin!
I was thinking about Sprint but they still have not they greatest service where I live, of course that may change in a few years.
My current AT&T bill is 150 per month and that is unlimited text, talk, 3GB data, and phone insurance for 3 phones.
The coworker that sits next to me at work has an iphone 6 and an ipad has verizon and pays 110-120 per month, I only know this because she complains every time she pays it, of course she does this at work and on company time.
