I have ATT: $100 a month for fantastic coverage and speed.
boyfriend has sprint: terrible speed and battery life, likely because of the coverage. Unlimited data though.
friend with verizon: voice OR data. still expensive.
friend with tmobile: fast, cheap, great coverage and call quality.
I'm going to tmobile. I just hope they release it in august.
I've had AT&T since the first iPhone and since I have a tower about a block away from me, I will be staying with AT&T. Their service has always been good for me and I can't think of any complaints over the years.
Between sticking with AT&T and changing over to T-Mobile. Just found out my job is finally offering all employees a chance to get cell phone service through them. If I could get a better payment plan with slightly more features than I have now (and ensure that this is my phone and not a company phone so to speak) maybe I will jump.
If that doesn't work for me, then I might try T-Mobile's non contract option come november when AT&T contract expires at that time.
Sprint I will never, ever go near again. And Verzion isn't my favorite company.
AT&T. Really no reason to switch. They mostly have LTE here, and the places that don't have LTE still have HSPA+, which I've tested at 8-9 Mbps at times. T-Mobile would be cheaper but their indoor coverage isn't as great. Plus, each of the lines on the account expire at a different time.
Not thinking about getting a 5S yet. No such thing is available right now, so I can't decide if I'd want one. But I like my 4S on 5.1.1, so I may not upgrade
