The Moto G comes in 2 GSM flavours, the "US" version and the "Global". The "US" variety supports the band 4 "AWS" data frequencies used by T-mobile and others, while the "Global" doesn't (but adds band 1 (2100Mhz) that is used internationally. When I saw that the major Canadian carriers were selling the "Global" variant, I assume it supported some GSM band used by Telus/Bell that the "US" didn't. But as far as I can tell, the Telus/Bell/Rogers use band 2 (1900) and band 5 (850) for their 3G networks, and the band 1/band 8 support of the "Global" variant isn't needed? Am I missing anything with frequency usages? Suspicious me is thinking that they might have chosen the "Global" in part to prevent the phones from walking over to the smaller AWS carriers (Wind, Mobilicity) etc? "Global" owners have better roaming options in Europe and elsewhere, but worse choices here and the US.
