A perennial question in the wireless industry is how much data are customers using and how are customers paying for that data.

Thanks to a new partnership between FierceWireless and Strategy Analytics, we hope to shed some light on the situation. The below data, from Strategy Analytics’ AppOptix service, show how often Android wireless users stray from cellular networks and onto Wi-Fi networks—and how that differs among customers of Verizon, AT&T, T-Mobile and Sprint.

But perhaps more interestingly, Strategy Analytics’ data also offers a breakdown of customers’ service plans, showing the amount of cellular and Wi-Fi data consumed by unlimited data customers and how that compares to customers with monthly data allowances and pay-as-you-go plans.

Strategy Analytics’ AppOptix data comes from a panel of 4,000 Android phone users who agreed to let the firm monitor their data usage and also who provided their demographics and network plan information. Panelists also update their profile—including information on their data plan and device purchases—on a regular basis.
