Every cell tower is different, every region is different, good
performance in one region on one carrier, maybe the exact opposite in
another region on that same carrier. That's quite a bit of data
(assuming 1-2mbps...not sure what "digit megs" are) you're trying push
through a cell network especially 3G. Is it possible your Verizon
testing is on Verizon's 4G network while Sprint's is 3G?
