US wireless data growth is slowing—even as usage hits a record 159.3 trillion MB
Dealer takeaway: Data usage is still exploding, but the rate of growth is cooling. That changes how you sell. The next wave isn’t just “bigger plans” for phone users—it’s AI traffic, fixed wireless home internet, and connected devices (wearables, sensors, trackers). Dealers who package experience + reliability will win more than dealers who only pitch “unlimited.”
What CTIA says the numbers look like
CTIA’s latest report highlights a record-setting milestone: in 2026, US users accounted for 159.3 trillion megabytes of wireless data.
The growth is still big—but it’s slowing compared to the last couple of jumps:
2023: 100 trillion MB (up 26T MB vs the year before)
2024: 132 trillion MB (up 32T MB vs 2023)
2026: 159.3 trillion MB (up 27.3T MB vs the prior figure cited)
In other words: Americans are using more wireless data than ever, but the pace of growth has eased.
Still massive: the “two-year” view is the real story
Even with slower year-over-year growth, CTIA’s framing is clear: wireless data usage is up nearly 60% in just two years. The networks are carrying dramatically more traffic than they were a few years ago, and CTIA expects the trend to continue.
AI is the next demand wave (and it won’t look like normal phone usage)
CTIA forecasts wireless data demand could be four times higher by 2032, with AI becoming an increasingly important source of network traffic. The report notes AI-related traffic is growing much faster than traditional wireless traffic and could eventually represent a meaningful share of broadband traffic.
Dealer translation: customers may not “feel” AI as a line item, but they will feel it as more always-on services, more background syncing, more video-heavy experiences, and more connected-device usage.
More spectrum + more infrastructure (and small cells are doing heavy lifting)
CTIA argues the industry will need more licensed spectrum and more physical infrastructure to keep up. US wireless providers reportedly spent nearly $30B in 2025 expanding network capacity, and total US wireless infrastructure investment has surpassed $763B—with about one-third of that coming since 5G arrived in 2018.
It’s not just towers. CTIA says the number of small cells is up nearly 120% since 2018, and small cells now represent nearly 40% of US wireless cell sites. Small cells are lower-power, shorter-range deployments that help add capacity where towers aren’t practical.
It’s not just phones: IoT + fixed wireless are driving real traffic
CTIA’s report emphasizes that smartphones and tablets aren’t the only drivers anymore:
The US now has 600M+ wireless connections (almost two per person)
46% of connected devices are non-phone devices (wearables, industrial sensors, robotics, and more)
Fixed wireless is a major contributor: for the fourth straight year, CTIA says virtually all net growth in US home broadband came from fixed wireless
Nearly 16M Americans now subscribe to 5G Home Internet, with 3.9M new subscribers added in 2025
Dealer playbook: how to sell in a “slower growth” data world
1) Stop selling “more data” and start selling “better experience”
Wi‑Fi calling setup + testing
Home Wi‑Fi optimization (router placement, mesh options)
Device upgrades that improve real-world performance (modem, antennas, Wi‑Fi standards)
2) Build a connected-device attach strategy
With nearly half of connections being non-phone devices, dealers should treat wearables and trackers as default add-ons:
Smartwatch pairing + plan add-on
Trackers for luggage/keys/bags
Business IoT basics (asset tracking, sensors) for SMB customers
3) Offer a fixed wireless comparison consult
Customers are already choosing 5G Home Internet in record numbers. Dealers can win by helping them compare:
Speed vs latency expectations
Streaming and gaming fit
Coverage and placement realities
Backup internet options
Bottom line
US wireless data usage is still growing and just hit a record 159.3 trillion MB—but the growth rate is slowing. The next big demand drivers are AI, fixed wireless broadband, and connected devices. Dealers who shift from “unlimited hype” to experience, reliability, and connected-device bundles will capture the next wave of revenue.
