Xfinity Mobile has grown rapidly since the service debuted in 2017, while Comcast’s cable subscriptions have dropped steeply. Broadband usage has leveled off. Comcast reports mobile growth by the number of wireless lines, with each customer having about two lines on average, but tracks cable and broadband by number of customers.

The 2026 mobile and video figures are from Comcast's second-quarter earnings report. Comcast only reports its total broadband customer count, including business subscriptions, in its annual report.
