More specifically whats the difference between the SE T610 and the SE T616
T610 - 900/1800/1900
T616 - 850/1800/1900
If all carriers in the US are 1900 - then why do we have two models of the same phone?
AT&T and Cingular use the 850 bands in some areas. T-Mobile has no plans to use the 850.
Where is the simple common sense of standardization!!!! Jeez!!!!
Within each band, and for each given area of the country, the bands are sub-divided into sections that companies can own a license to. There are two 850 licenses and six 1900 licenses for any given area.
Each license was auctioned off years ago - they're all owned now. The only way to get a license now is to buy one from someone willing to sell. When someone is willing to sell a wireless license, (not often) it's usually for billions of dollars.
So... why don't AT&T and Cingular use 1900 everywhere? Because they...
