Which network does the Wanderly USA eSIM use?

T-Mobile or AT&T depending on plan. Both are tier-1 US carriers with nationwide 5G in cities and 4G along the interstates.

Will it work in national parks?

Coverage in parks varies widely. Yellowstone, Zion and Grand Canyon have signal near visitor centers. Backcountry and slot canyons typically do not — download offline maps.

Wanderly USA plans are data-only, matching how most travelers use their phones today. Use WhatsApp, FaceTime, iMessage or Google Voice for calls.

How much data for a 2-week US road trip?

15–20 GB for a coastal city trip. Choose unlimited for road trips through Utah, Arizona, Wyoming or Montana where you rely on maps constantly.

Yes, Wanderly USA plans support tethering. Handy for laptops in coffee shops or sharing with travel companions in the car.

Great for USA travel

Set it up before my flight and had data straight away. Coverage across New York and LA was solid. Only minor issue was slightly slower speed in some rural areas, but that is expected.

United States eSIM plans at a glance

Wanderly lists 41 fixed-data United States plans, ranging from 1GB up to 100GB over 7 to 365 days. Prices start at $2.99, and the lowest cost per gigabyte is $0.76/GB on the 50GB 30-day plan.

Unlimited day-passes are also available from $1.99 per day, billed per day rather than per gigabyte. All 55 United States plans can be topped up without reinstalling the eSIM.

Every plan is data-only and installs from a QR code, so your home number stays active on its own line. Validity starts when the eSIM first connects to a network in United States, not at purchase, which means you can install before you fly.

🇺🇸 About eSIMs in United States

The United States is huge, and network quality varies more than most travelers expect. Wanderly USA eSIM plans connect to T-Mobile or AT&T — the two networks with the best national footprint — giving you strong 5G in every major city and continuous 4G along the interstates. Coverage in rural New Mexico, Utah backcountry, and deep in national parks is thinner regardless of carrier, so plan accordingly.

Data needs are usually higher than travelers guess: Uber and Lyft, Google Maps with live traffic, ticket apps for stadiums and museums, and Yelp for every restaurant decision. For a two-week New York + Miami + LA trip, 15–20 GB is comfortable. Road-trippers doing national parks want unlimited so navigation and camping-app research do not run out.

Compared to buying a local prepaid SIM (which usually requires a US address), the eSIM installs in minutes and works everywhere from JFK to the Grand Canyon rim.

How to activate your eSIM in United States

1
Install before boarding
Add the eSIM at home while on Wi-Fi. Do not activate yet — first data use starts the plan clock.
2
Switch on arrival
After landing at JFK, LAX, MIA or ORD, make the USA eSIM your data line and enable Data Roaming.
3
Save offline maps
Download offline Google Maps for national parks and remote road-trip stretches (Utah, New Mexico, Montana).
4
Keep home SIM for calls
Wanderly USA plans are data-only. Use WhatsApp, FaceTime or your home SIM voice line for calls.
