Holafly USA eSIM Review: United States Unlimited Data + Code THEDUFRESNES (Up to 30% Off)
Last Updated:
If you're visiting the United States and wondering how to get online without buying a US SIM or paying your home carrier's roaming rates, a travel eSIM is the easy answer. We used Holafly in the US ourselves during a 5-night stay in 2024, breaking up a long haul from Costa Rica to Thailand — so this is a real, if honest-about-its-length, firsthand review rather than a spec sheet.
Our honest experience using Holafly in the USA
We'll be straight about the scope: our US Holafly use was a 5-night stay in 2024, not months of cross-country road-tripping, so we're not going to pretend we've stress-tested every corner of the country. What we can tell you is what it did on the ground — it connected the moment we landed, carried maps and ride-hailing through a busy transit stop, kept us reachable while we sorted onward flights, and did it all without us hunting for a US SIM in an unfamiliar airport.
For a visitor passing through or staying a week or two, that's exactly the job: data that works instantly, so the first thing that functions after a long flight is your map and your ride. It did that reliably for us.
Why use a Holafly eSIM in the United States?
- No US SIM to buy
- Buying a US prepaid SIM as a visitor means finding a store, sometimes ID, and setup. A Holafly eSIM installs by QR code before you fly — connected on arrival, nothing to buy locally.
- Unlimited data, no rationing
- The US eSIM is unlimited, so you're not watching a meter across maps, rideshare, and staying in touch back home. For a trip where you're constantly navigating a new place, that matters.
- Keep your home number
- Holafly runs alongside your existing SIM, so your normal number stays active for calls and the security codes banks and airlines text you — data on Holafly, number on your home SIM.
- Coverage on major US networks
- Holafly connects to major US networks with strong coverage in cities and populated areas. As anywhere, remote and rural stretches depend on what the local network physically reaches.
Who needs a US travel eSIM?
- International visitors to the US — the core case: data without a US SIM or expensive home roaming.
- Travelers passing through — layovers and short stays where a local SIM isn't worth the hassle (our exact situation).
- Anyone who wants unlimited — heavy map, rideshare, and social use without a data cap.
If your trip also crosses into Canada or Mexico, don't buy a US-only eSIM — our North America regional guide covers all three on one plan.
USA eSIM pricing with THEDUFRESNES
The USA eSIM sits on Holafly's standard price ladder — unlimited data, priced by the number of days. With the code you get 5% off, so a 3-day plan starts at $11.31. For the full day-by-day breakdown (3/5/7/10/15/30 days), see our USA eSIM price guide.
If you travel often or stay longer, Holafly Plans can be better value — 10% off monthly and up to 30% off annual with the code, covering 160+ destinations on one subscription with unlimited hotspot.
What US travelers report
Beyond our own stay, the sentiment we see from travelers on Reddit and traveler forums is consistent: visitors to the US are relieved to skip buying a local SIM and to land already connected, and the unlimited data is valued most by people leaning on maps and rideshare all day in unfamiliar cities. The balanced note is the usual one — it costs more than a bare-bones capped SIM, and "unlimited" carries a fair-use policy, as every unlimited plan does. For the convenience of instant, uncapped data, most travelers find it worth it.
Holafly USA eSIM FAQ
Does Holafly work well in the USA?
Yes — it connects to major US networks with strong coverage in cities and populated areas. In our 5-night stay it worked reliably for maps, rideshare, and staying connected. Remote and rural areas depend on local network reach, as with any provider.
How much is the Holafly USA eSIM?
It's on Holafly's standard ladder — unlimited data priced by days, from $11.31 for 3 days with code THEDUFRESNES (5% off). See our USA price guide for every duration.
Do I need to buy a US SIM as a visitor?
No. A Holafly eSIM installs by QR code before you fly and activates on arrival — no US store, no local SIM, and your home number stays active alongside it.
Can I hotspot with the USA eSIM?
Destination eSIMs allow around 1 GB/day of sharing. For heavy tethering or a family, Holafly Plans Unlimited includes unlimited hotspot.
What if I'm also visiting Canada or Mexico?
Use the North America regional eSIM instead — it covers the USA, Canada, and Mexico on one plan, so you don't buy a separate eSIM per country.
Is THEDUFRESNES a working Holafly code?
Yes — our official ambassador code, verified August 2026. 5% off destination eSIMs like the USA, 10% off monthly Plans, and up to 30% off annual Plans (Holafly's 20% annual promotion plus the 10% code).
Bottom line
For a visit to the United States, the Holafly USA eSIM is a clean, unlimited, no-friction way to stay connected — buy it before you fly, land connected, keep your home number. It worked reliably for us on our stay, and for the convenience of instant uncapped data it's an easy recommendation for visitors. Either way, THEDUFRESNES saves you at checkout.
