TCS New York City Marathon
50,000+ runners, 1 million+ spectators across all 5 boroughs. Race day is November 1 — the busiest single-day event in New York City all year.
If your itinerary includes national parks (Yellowstone, Grand Canyon, Yosemite, Zion, the Great Smoky Mountains) or long drives on rural highways, expect substantial stretches without any mobile coverage regardless of network or provider. Visitor centres and entrance areas usually have signal; backcountry, canyon floors and valley roads often do not. Download offline maps before leaving urban areas — Google Maps and Apple Maps both allow full offline downloads for specific regions. Save all accommodation addresses, booking confirmations and navigation waypoints offline before departure from any city. Among the providers on this page, Airalo routes via both T-Mobile and Verizon with automatic switching, pairing T-Mobile's urban 5G strength with Verizon's rural reach for mixed rural and urban itineraries.
All US-purchased iPhones from iPhone 14 onwards (2022–present) have no physical SIM tray — eSIM is the only option for cellular connectivity. International versions of the same models retain a SIM tray. Apple does not exchange US models for international ones; the eSIM-only configuration is permanent. If you are buying a new iPhone in the USA and need physical SIM compatibility abroad, verify the model's regional variant before purchase.

eSIM — the USA
Network coverage in the USA
Three national networks dominate the US mobile market: T-Mobile, AT&T and Verizon. For urban travel — New York, Los Angeles, Chicago, Miami, San Francisco, Las Vegas, Orlando — all three deliver fast 4G/5G. T-Mobile has the widest mid-band 5G footprint and leads in cities. AT&T covers urban and suburban areas well, with particular strength in the South and Southeast. Verizon is the strongest option for remote and rural areas, especially in the Northeast, Midwest and Great Plains.
On this page, Airalo routes via T-Mobile and Verizon, Roamless via Verizon, AT&T and T-Mobile, and Yesim via Verizon and AT&T. All three list Verizon, the strongest network for rural and remote areas — useful on cross-country road trips (though Verizon access via travel eSIMs can vary in practice). Even so, no travel eSIM provides reliable coverage deep in national parks or remote backcountry, so download offline maps before any road trip regardless of provider.

Roaming or eSIM — should you buy?

VPN, passwords and documents
The USA has no internet restrictions. A VPN can be useful on public Wi-Fi (cafés, hotels, airports) to keep your browsing private from the network operator. A password manager can also be useful. A secure cloud backup of your passport, insurance certificate and hotel bookings is also useful — keep an offline copy too. None of these are mandatory.
