How much data customers are using and how customers are paying for that data are perennial questions in the wireless industry.

Thanks to a partnership between FierceWireless and Strategy Analytics, we hope to shed some light on the situation. The data below, 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.

This is a recurring, monthly feature from FierceWireless. Click here for numbers from December 2017 and click here for January 2018 numbers. The numbers can fluctuate up and down from one month to another due to a variety of factors including holidays, movie and TV releases, weather and other issues. For example, cellular usage is down across the board for all carriers in January when compared with December—a drop that also happened last year.

The information below is from February 2018. We hope you enjoy it!

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