In a lot of the US you don't get an "E for Edge" you get a "No Service." I was just in Mansfield Ohio and my freind's T-mobile phone was more or less useless and had to be tethered to mine the whole trip, mine (which uses one of the two larger carriers with better rural coverage, mostly because of where I grew up) worked enough that we could occasionally get text messages out, we often had to find a cafe if we needed a new route or map tiles though.
