said by patcat88:said by jay_rm:Too be technically correct, that statement SHOULD note that this is just the UMTS 3G part of T-Mobiles US spectrum. T-Mobile USA is also the LARGEST occupant of the 1900 MHz band, used mostly for 2G+ services, and uses pretty much the same dual-band GSM RF architecture handsets as ATT Mobility. A typical T-MO handset can roam on ATT Mobility and vs-vs
But does it in-market roam on ATT? Could've would've should've, DOES IT?
WiMAX says WiMAX works from 2 GHZ to 66 GHZ. Will there ever be a product that will do that? No.
UMTS and GSM also have many many bands in their standards that will never find a Nokia, Samsung, or LG phone for.
