US smartphone users consumed 37.6 GB of data on a monthly basis, slightly up from 33.9 GB in the previous quarter. Wi-Fi usage typically accounted for over 80% of total data consumption, though it’s been declining (74% in Q4 2019) in parallel to the increase in cellular data consumption fueled by unlimited data plans.
Unlimited data plan customers consume more than double the amount of data consumed by customer who are on bucket plans (i.e. 5GB or 8GB plan). Similarly, customers on postpaid accounts consume 42% more than those users who are on prepaid accounts.
