According to a coming study by wireless billing Vendor Validas, Verizon Wireless smartphone users officially use more data than iPhone users on the AT&T network. According to Validas, the average monthly wireless data consumption for Verizon Wireless Smartphones is 421 megabytes per month, versus 338 megabytes per month for iPhones. Some other key points Validas found:

•More than 54 percent of Verizon smartphones consume less than 200 MB per month, versus slightly more than 52 percent of iPhones.

•Nearly 46 percent of Verizon smartphones consume more than 200 MB per month, versus nearly 48 percent of iPhones.

•More than 4 percent of Verizon smartphones consume more than 2 gigabytes per month, as opposed to just 1.6 percent of iPhones.

•Only 2/10ths of 1 percent of both Verizon smartphones and iPhones use more than 5 GBs per month.

•A nearly even percentage of users consume no data at all in a given month - 3.4 percent for Verizon smartphones versus 2.9 percent for AT&T iPhones.

Of course all of these numbers are going to change very quickly as video via smartphone use (Hulu, Netflix streaming) accelerates and next-generation LTE networks are deployed. In a blog post, Validas offers additional data for those interested, including the fact that AT&T still sees the highest percentage of overall users with data usage -- at 71.2%. The study was conducted between January and May of 2010 and included more than 20,000 consumer wireless bills.
