AT&T might be the first carrier you think of when you picture the largest mover of wireless data in the US, but according to a new study published by ABI Research, the honor actually belongs to Verizon. In fact, not only does Verizon beat out AT&T, but so does Sprint with the two networks having handled a grand total of 63% of wireless data in 2009. To give you a idea of how much data that equates to, last year Verizon and Sprint moved a whopping 16 billion MB (or 15,625,000 TB) more data than AT&T. ABI claims the numbers have more to do with AT&T’s smaller 3G coverage and the prevalence of data cards on the two EV-DO networks, but it is predicting AT&T will be able to overtake Sprint come 2012. What do we think, class?
