Holafly vs AeroSims for the USA (2026): Two Networks vs One — and the Package Math

Updated July 2026 · Prices verified at provider checkouts and subject to change

New York to a Utah national park is a 3,500 km network stress test. Here’s the honest USA comparison: on 7-day unlimited, Holafly is actually a couple of dollars cheaper — but AeroSims rides both T-Mobile and Verizon and its 10 GB package costs less than half of either unlimited plan. Which matters more depends on your trip.

Why two networks matter more in America than anywhere else

In Manhattan every network is great. On the I-70 through Utah, or between park entrances in Wyoming, the map fragments: T-Mobile dominates cities and interstates, Verizon owns rural America. A single-network eSIM is a bet on where you’ll stand; AeroSims’ automatic switching between both is the closest thing to full-country insurance a traveler can buy. If your USA plan includes a road trip, this row of the table outweighs the $2 price difference on unlimited.

The package math for a two-week USA trip

US hotel, café and mall Wi-Fi is everywhere, so mobile data is for the gaps: maps, rideshares, tickets, uploads. 10 GB for $12.90 covers a typical two-week city trip; 20 GB for $23.90 covers heavy use — both under half of one unlimited week. Uber, Lyft, OpenTable, mobile boarding passes: none of it is data-hungry. The traveler who genuinely needs unlimited in the US is the one hotspotting a laptop daily — and that traveler should read the fair-use rows above carefully, on both sides.

The honest unlimited paragraph

AeroSims’ USA unlimited gives 3 GB/day at full speed, then throttles to 1 Mbps until midnight — enough for maps and messages, not for streaming. Holafly doesn’t publish its USA cap; independent reviews report generous but undisclosed thresholds, and its 7-day plan is a couple of dollars cheaper. So: if you stream video all day every day, Holafly’s USA unlimited is the better buy. If you want predictable terms, dual networks and a refund guarantee, AeroSims is — and if you’re honest about your usage, the $12.90 package beats both.

USA eSIM questions travelers ask

Which is cheaper for the USA — Holafly or AeroSims?

On 7-day unlimited, Holafly by ~$2. On overall value, AeroSims’ packages: 10 GB for $12.90 is less than half of either unlimited week — the right buy for most visitors.

Which networks does the AeroSims USA eSIM use?

T-Mobile and Verizon with automatic switching — including 5G. Verizon’s rural coverage is the key advantage on road trips and in national parks.

Does it work for a New York + national parks combo trip?

Yes — cities are excellent on both networks, and the dual-network setup keeps you connected on interstates and in gateway towns. Deep backcountry has no signal on any provider; download offline maps for trailheads.

Can I hotspot my laptop?

On AeroSims, yes — no separate tethering cap on either plan type (the daily fair-use still applies on unlimited). Holafly limits hotspot use per day.

When does my plan start?

When the eSIM first connects to a US network — not at purchase. Install at home before you fly; the QR arrives by email seconds after checkout.

Bottom line

For the USA, buy by trip type: packages for cities, dual-network for road trips — and only pay for “unlimited” if you’ll truly stream all day (in which case, Holafly’s sticker price wins that narrow race). Every other traveler saves $15+ with the 10 GB package.
