Best eSIM for the United States

Prices in the United States

The travel eSIMs are competitive here for small plans; for a week of heavy use T-Mobile’s own tourist eSIM is the comparison to make. How the three providers compare across all fifteen destinations is in our main eSIM comparison.

Which network you get

All three US networks appear across the providers:

• Airalo lists T-Mobile as the primary network and Verizon as a second, with the eSIM switching between them by availability and speed. No 5G or hotspot statement. Airalo says its US eSIM covers Hawaii and Puerto Rico with limited availability in Alaska.
• Holafly lists AT&T and T-Mobile, with 5G where available and hotspot sharing capped at 1 GB a day.
• Saily does not name its network; it states 5G depending on the local provider and hotspot use with no restrictions. It sells a day-by-day unlimited plan from $3.49 for a single day.

Buying a local SIM instead

There is no federal SIM registration, and the operator pages ask for none.

• T-Mobile Prepaid U.S. Pass: $25 for 7 days, $30 for 10 and $35 for 14, plus taxes and fees, with unlimited 5G data (50 GB of premium data), 14 to 28 GB of hotspot data, and unlimited calls and texts in the US, Mexico and Canada. T-Mobile’s FAQ: “No. There’s no paperwork or in-store visit required.” It activates at purchase, so buy it when you land, on an unlocked eSIM phone.
• Mint Mobile’s three-month plans start at $15 a month for 6 GB, paid upfront, as an eSIM or a shipped SIM.
• AT&T Prepaid is sold online and in stores; its bring-your-own-device pages require an unlocked phone compatible with AT&T’s LTE bands. We found no official airport page listing SIM counters.

Before you land

The US question is the phone, not the paperwork: a handset bought for another market may lack the LTE and 5G bands the US networks use. AT&T’s own guidance lists the bands its network needs; T-Mobile requires an unlocked, eSIM-capable device.

• Install on Wi-Fi at home; Airalo allows 365 days from purchase to start, Saily 180.
• These are data-only plans. Keep your home SIM active for the text messages your bank and your airline send, with data roaming switched off on it.
• Carry your onward reservation in a form that opens without a connection: the check-in desk asks for it before the eSIM is on. The United States’s onward-ticket rules are on their own page, and the free checker covers your passport.
