Best eSIM for United States
Instantly compare and calculate the best local network deals for your trip to United States.
Find the perfect plan for United States
Check hotspot limits before you rely on tethering in the US
Most US travel eSIMs run on AT&T or T-Mobile and allow tethering, but the terms vary more than the marketing suggests. Holafly permits sharing only 1GB per day and excludes Baja California from coverage, while the plans labelled unlimited from Airalo, Saily, Nomad and aloSIM all cut to reduced speeds after a daily allowance (2GB to 5GB depending on the provider). If you plan to work off a laptop, compare the daily caps in the table below rather than the headline price.
Staying connected in United States
What the coverage maps do not tell you, and what you will actually use the data for.
Where the signal actually drops
Urban and interstate coverage on AT&T and T-Mobile is strong, but the United States has more genuine dead zones than travellers expect. Large stretches of the interior west drop to nothing: the Utah and Nevada desert routes, much of Wyoming and Montana away from the interstates, and the national parks. Yellowstone, Death Valley, Big Bend and the Grand Canyon rim have signal only in patches around visitor centres, and canyon floors have none at all.
What you will use your phone for here
Practical daily use is navigation, rideshare (Uber and Lyft), and increasingly restaurant ordering by QR. Domestic travel leans on airline apps for boarding passes and delay notifications. Tipping and payment are still card-first rather than phone-first, so unlike Asia your data is convenience rather than a prerequisite for spending.
Before you go
Download offline maps before any road trip through the west. This is the single most common connectivity mistake in the US, and unlike a European road trip there may be no signal for a hundred miles to fix it. Note also that eSIMs sold for the US are usually data-only, so they will not carry a US number for the SMS verification some local services demand.
How much data you will actually need
Low to moderate in cities, but road trips push it up because navigation runs continuously for hours at a time.
