I've always wondered how AT&T is able to get away with saying they have the best mobile coverage. My experience has been that their coverage is terrible -- except at work where we have a microcell.
Ever notice the fine print on AT&T's "more bars in more places" campaign?
The fine print says "Based on global coverage".
Well, duh, of course AT&T wins over Verizon and Sprint if you count coverage in France! All cell phone providers are legally required to use use GSM in Europe. Very few overseas wireless companies use CDMA like Sprint and Verizon do here in the US.
Not that I'm defending Verizon, or any other vendor, by the way. Coverage in buildings sucks unless you have a microcell. VoIP over WiFi... it's the future.
