See matching unlimited plans →⚠️ "Unlimited" almost always has a catch
Nearly every "unlimited" USA eSIM applies a Fair Use Policy (FUP): you get a daily high-speed allowance (commonly 2–10 GB), after which your speed is throttled — often down to 1 Mbps or lower. That's fine for maps and chat, but not for HD video or tethering all day.
Light use (maps, chat, social)
~0.5–1 GB/day — most FUP caps are plenty.
Heavy use (video, tethering)
3 GB+/day — pick a high FUP cap or a large fixed-data plan instead.
Tip: sort by most high-speed data above to surface plans with the highest daily cap.
Unlimited USA eSIM: provider notes
- Holafly — popular unlimited plans; FUP typically throttles after ~2–3 GB/day. Some plans allow hotspot, some don't.
- Yesim — unlimited options with a relatively generous FUP; usually pricier.
- Airalo — mostly fixed-data plans; its unlimited options vary by FUP, check the plan detail.
- Saily / Nomad / Ubigi — competitive US coverage; compare live to spot the cheapest per-GB.
Prices and FUP change often — that's why we send you to a live comparison instead of a static list.
USA unlimited eSIM — FAQ
Is there a truly unlimited data eSIM for the USA?
Most "unlimited" plans have a daily high-speed cap (FUP) and then throttle. Truly uncapped plans are rare — always read the FUP. Sorting by "most high-speed data" helps you find the highest caps.
Does an unlimited USA eSIM support hotspot?
Some do, some don't. If you need tethering, use the hotspot filter above so we only show hotspot-enabled plans.
Will my phone work with a US eSIM?
Any eSIM-capable phone works (iPhone XS/XR and newer, most recent flagship Androids). Not sure? Check your iPhone here.
eSIM vs a US prepaid physical SIM?
An eSIM installs before you fly and works on landing — no store visit. A physical prepaid SIM makes sense if you need a US phone number. For data-only travel, eSIM is usually cheaper and easier.
