850/1900/2100/AWS - Quad band 2G, 3G and 4G
Say what 4g?
If they are on Tmobile they are probably talking about the new HSDPA and HSDPA+ that Tmobile is supposedly rolling out in certain parts of the country. Right now though I think Tmobile is just doing HSDPA so maybe they are trying to claim that is 4g? Who knows the company looks like it was thrown together in a weekend meeting between 3 guys and a few six packs. -- Looking to get into Avaya telco if you might be in that field hit me up I have a lot of questions.
