Which US eSIM is best? AT&T, T-Mobile, Verizon and national park signals

How many US eSIM options are there now

Our US destination page has nearly 60 eSIM plans, ranging from 5 to 30 days — US eSIMs don't have those ultra-short 1 to 4 day plans like Vietnam and Australia.

eSIMs are almost all total data plans (sharing one pool for the whole trip), with very few daily fixed options. So when calculating data, think in terms of “how much total for the whole trip”

⚠️ If you want “unlimited data” you need to choose a physical card. All our unlimited plans for the US are physical SIM cards, with none available for eSIM. To get unlimited, you need to factor in mailing time (1–3 working days).

Real-time plan details and prices are available on the US destination page.

How to choose among the three major networks

The main networks in the US are T-Mobile, AT&T, and Verizon. 5G coverage is extensive in cities and along interstate highways, with little difference among the three networks.

However, there are large areas with no signal in national parks (Grand Canyon, Yellowstone, etc.), deserts, and mountainous regions. For road trips and itineraries involving national parks, AT&T and Verizon generally offer better rural coverage than T-Mobile. It's recommended to choose a plan that includes them.

Before setting off on a自驾 journey, make sure to download offline maps — like in the Australian Outback, these areas have no signal for any network, and switching networks or buying a larger plan won't solve the issue.

Want unlimited data? Pay attention to two things

• Unlimited plans in the US are only available with physical SIMs — for those who want to buy and use eSIMs immediately, you'll need to go with a total data plan, and you'll have to estimate your usage yourself.
• “Unlimited” usually isn't truly unlimited speed: typically, the first few GB are at full speed, after which the speed is reduced but you can still use data. Each plan's description clearly states how it works.
• Short trips may not be worth it: for the same price, a total data plan might offer more full-speed data than the full-speed allowance of an unlimited plan. It's only worth the premium for longer trips where usage is unpredictable.

How many GB do you need?

• City-centric travel (New York, San Francisco, Los Angeles) → Navigation + communication + social media, approximately 1GB daily is enough.
• Road trips → With navigation running all day, it's recommended to budget 1.5–2GB daily.
• Constantly streaming videos or live broadcasting → Daily 2GB or more, or consider an unlimited plan.
• Unsure? Use our data usage calculator to estimate.

Days vs. Itinerary

• Days are counted from the first connection to a US network, not the purchase date — buying early won’t hurt.
• Add a buffer day: Long flights, transit delays, itinerary changes — actual usage days often exceed estimates.
• Planning to visit Canada or Mexico too? Look at US+Canada or US+Canada+Mexico plans; no need to switch cards.

eSIM or physical card?

If your device supports eSIM (dial `*#06#` to see the EID), choose eSIM: After payment, a QR code is emailed instantly; use it upon landing and enabling roaming.

US physical cards account for over half of sales, and unlimited plans are only available as physical cards. Ideal if your device doesn’t support eSIM or if you want unlimited data. Free local postage in Hong Kong, arrives in 1–3 working days — remember to factor in mailing time.
