Which carrier is better at iPhone plans AT&T or T-Mobile?

Verizon.

Verizon sucks.
i say t-mobile since they have the tmobile JUMP and really good prices

I vote for AT&T, they have free mobile hotspot in metro area or when you're in Canada's major cities.

To be honest for an iPhone go
With sprint unlimited everything for 80 a month I use it I have lte every where I go

I have an iphone 4 and I'm on Verizon and its good but I haven't had any other carrier so haha
