The Myth of Cellphone-Only Users

Key Takeaways

• 16% of Americans rely solely on smartphones for broadband (2025)
• Income under $30k: 34% use only cellphone broadband
• Income over $100k: only 4% use cellphone as sole broadband
• Average home broadband consumes 767 GB/month vs 23 GB cellular
• Cellular plans cap at ~50 GB, limiting heavy‑use households

Pulse Analysis

The Pew Research survey reveals a stark income‑based divide in broadband access. While 16% of U.S. adults reported using a smartphone as their only internet source in 2025, the prevalence spikes to 34% among households earning less than $30,000 and drops to just 4% for those above $100,000. This pattern shows that the so‑called "cellphone‑only" generation is largely a function of affordability rather than a generational shift toward mobile‑first connectivity. Low‑income families often forgo costly home broadband, opting for the mobility and lower entry cost of a data‑centric smartphone.

Data consumption further disproves the notion that smartphones can replace traditional broadband. OpenVault reports the average U.S. broadband household used 767 GB of data in 2025, while the typical cellular subscriber consumed about 23 GB. Even “unlimited” mobile plans throttle speeds after roughly 50 GB, and tethering caps often sit below 20 GB. Consequently, heavy‑use activities—streaming video, remote work, online schooling—remain impractical on a cellular‑only connection, forcing many users to rely on public Wi‑Fi or hybrid solutions.

For telecom operators and policymakers, these insights signal where investment is needed. Expanding affordable broadband options in low‑income neighborhoods can reduce reliance on inadequate cellular substitutes and close the digital divide. Meanwhile, carriers may explore bundled pricing that pairs modest home broadband with mobile data, catering to households transitioning as incomes rise. Understanding the economic drivers behind cellular‑only usage will be crucial for shaping future connectivity strategies and ensuring equitable internet access across the United States.
