Obviously not every country has 3G, but how far are we on the way toward a 3G/4G equivalent of 2G quad band? Are we there yet?
I've noticed that T-Mobile USA's 3G bands (UMTS (W-CDMA)/HSPA) operate using both 1700 and 2100 Mhz frequencies (at the same time) and India also uses 2100 Mhz for its 3G, so that seems to be a happy coincidence for those who travel between both countries
Other countries also use the UMTS 2100 band
, I see. So it may be a matter of picking your countries from the start and not aiming for universal 3G.
Otherwise I am not seeing much of a movement toward a universal 3G/4G phone, but maybe I am misunderstanding things and will appreciate any insights.
