Google Fi and US Mobile both appeal to people who manage their service online and want more than a one-size plan. Google Fi runs on T-Mobile (plus Wi-Fi) and is famous for working in 200+ countries. US Mobile lets you choose Verizon, Verizon Ultra Wideband, or T-Mobile, undercuts Fi on price, and includes taxes.
Quick answer
- Pick US Mobile for lower prices, network choice, taxes included, truly unlimited no-slowdown data (Premium $44), or the free 30-day trial.
- Pick Google Fi if you travel internationally a lot — data that just works in 200+ countries — or you’re deep in the Google/Pixel ecosystem.

Price: US Mobile wins clearly
For one line, US Mobile is dramatically cheaper — $25 standard unlimited vs Fi’s $50, and $44 truly-unlimited Premium vs Fi’s $65 — with taxes included while Fi adds them. Fi’s per-line price drops sharply on family plans (Standard $25/line, Premium $40/line at 4 lines), narrowing the gap for larger households. Light users: US Mobile’s $8 (2GB) and $17.50 tiers vs Fi’s Flexible $20 + $10/GB.
International: Fi’s whole identity
Fi’s Unlimited Premium includes high-speed data in 200+ destinations at no extra cost — land, turn on your phone, it works. US Mobile handles international well (calling to 180+, eSIMs in 140+ countries, ~20GB roaming on Premium) but as features, not identity. Cross borders often → Fi; mostly call abroad from home → US Mobile is plenty.
Network and data
Fi runs primarily on T-Mobile with Wi-Fi handoff. US Mobile lets you choose Verizon, Verizon UW, or T-Mobile and switch by eSIM — an option Fi doesn’t offer. US Mobile Premium is truly unlimited, with unlimited hotspot on Dark Star (AT&T) and 50GB on Verizon or T-Mobile; Fi Premium gives 100GB high-speed with a 50GB hotspot plus YouTube Premium and 100GB Google One.
