I give it an 8. I get some sort of signal everywhere I go. But in my house I get Edge data and a medium signal. When I had Verizon I had full 3G almost everywhere. But In our house my brother with an iPhone 3G gets a 3G signal. When I leave my house I'm back to 3G again.
For someone that has traveled all over, I give AT&T a 10. I've had AT&T on my personal phone for over 10 years. I had Verizon for my work phone for 5 years and then AT&T for the last 3 years. Both networks are comparable but AT&T had better coverage in Alaska and Hawaii. They are comparable in all the other states.
About an 8. Been with Sprint, T-mobile, Nextel, Cingular(Eventually AT&T of course). Out of all the carriers, AT&T was the best out here in Hawaii. When I was in the mainland, the places I visited, AT&T again had the better reception. The only exception was when I was stationed in Maine. Specifically in my house I had minimal bars. But was fine when near a window/outside.
9. Even after the update weeks back to realistically show the proper signal strength I still have 5 bars showing most of the time and service even in the middle of my grocery store
Had Sprint before anduch prefer AT& T
their network? well i'd have to rate it an 8. there's no place that i've been that hasn't gotten decent att signal.
their company as a whole? i'd give them a 5 at the most. they are a greedy company with horrible customer service and the only reason i'm with them is because of their network that i just gave an 8. haha
In northern NJ
AT&T 8 (iPhone 4)
I switched to AT&T for the iPhone and drop more calls in a week than I remember dropping with Verizon the 6 years I had them. Im hoping as others have said the coverage is better outside my home area. Heading to Las Vegas next week and Montana the week after.
