Flat data for the remote workers who tether all day and refuse to ration gigabytes. Here's who's genuinely unlimited — and where the fair-use small print bites.
Holafly is our pick for genuinely unlimited data — flat plans, no GB counter, priced per day across 200+ destinations. The honest catch with the whole category: "unlimited" almost always means uncapped volume with a fair-use full-speed threshold, and hotspot rules vary. We unpack exactly who's unlimited in our unlimited comparison.
The unlimited specialist: flat plans that don't cut you off, with broad destination coverage. Priced per day, so it's best for intense work bursts rather than your entire 180-day trip.

Three things to check before you assume "unlimited" means what you think.
Many plans give unlimited volume but throttle speed after a daily high-speed threshold (often a few GB). Truly flat plans don't — that's the premium you're paying for.
Some unlimited plans cap or throttle tethering even when phone data is uncapped. If you tether a laptop all day, confirm the hotspot allowance — see our tethering guide.
Unlimited is usually billed per day, so cost scales with trip length. Brilliant for a busy fortnight; pricey across a full 90-day stay versus a large metered long pack.
