eSIM USA: prepaid data for the United States, installed before you land
An eSIM for the USA is the simplest way to arrive in New York, Los Angeles, Miami, Orlando or Las Vegas with working mobile data from the moment the plane doors open. Instead of hunting for a carrier store at JFK or paying your home operator’s daily roaming pass, you buy a prepaid USA eSIM online, scan a QR code at home, and your phone connects to an American network automatically when you touch down. There is no physical SIM to swap, no contract, and your own number keeps working for calls and WhatsApp on your primary SIM.

Which networks does the USA eSIM use?
GlobaleSIM’s United States plan connects to AT&T, T-Mobile and Verizon — the three national carriers that between them cover the interstate network, every major airport and the big-city 5G footprint. Because the plan is not locked to a single operator, your phone can attach to whichever partner network is available where you are, which matters on a road trip between cities or in smaller towns where one carrier is stronger than the others. In dense areas you will typically see 5G; along highways and in rural stretches expect 4G LTE. Coverage in national parks and remote desert or mountain areas is limited on every US network, so download offline maps before you head out.
Plans and prices for the United States
United States eSIM data plans start from $4 for 1GB, and go up through 2GB, 3GB, 5GB, 10GB, 15GB and 20GB. Validity scales with the plan: 1GB is valid for 7 days, 2GB for 10 days, 3GB for 14 days, 5GB for 21 days, and the 10GB, 15GB and 20GB plans for 30 days. For a typical one- or two-week holiday with maps, ride-hailing, social media and a few video calls, 5GB to 10GB is the sweet spot; remote workers and families sharing a hotspot should look at 15GB or 20GB. The validity clock only starts when your device first connects to a supported US network, so you can install the eSIM days before departure without losing a single day.
A US phone number for calls and SMS
Most travel eSIMs are data-only. GlobaleSIM’s USA eSIM is different: add a voice-minutes plan (+100, +200 or +300 minutes) at checkout and you receive a dedicated US (+1) phone number by email. That number lets you call restaurants, hotels, car-rental desks and local friends, receive SMS verification codes, and be reachable from the US without anyone paying international rates. The number is an international US line, so include the +1 country code even when dialing another US number.
Installing your eSIM for the USA
- Buy online, receive the QR code by email within minutes — nothing is shipped.
- Install over Wi-Fi before you fly: Settings → Cellular → Add eSIM on iPhone, or the equivalent on Samsung Galaxy and Google Pixel.
- On arrival, turn on data roaming for the eSIM line and set it as your data line. Your primary SIM stays active for your own number.
- Hotspot and tethering are supported, so a laptop or a second phone can share the connection.
- Running low? Top up from the GlobaleSIM dashboard or the app at any time, with 24/7 human support on WhatsApp if you need help.
Tips for using mobile data in the United States
Ride-hailing, mobile boarding passes, contactless payments and turn-by-turn navigation are the biggest data users on a US trip. Parking apps, theme-park apps and sports-venue tickets are increasingly phone-only, so a reliable connection saves time as well as money. Free Wi-Fi is common in hotels, cafés and malls but is rarely fast or secure; treat it as a backup and keep the eSIM as your main line. If your trip continues into Canada or Mexico, choose the North America regional plan instead of the USA-only plan so one eSIM covers the whole route.
Why an eSIM beats roaming in the USA
Home-carrier roaming passes commonly cost the equivalent of $10–15 per day, which makes a two-week trip more expensive than a 20GB prepaid plan. Local physical SIMs require a store visit, ID and often a US address. A prepaid USA eSIM from GlobaleSIM removes both problems: transparent pricing paid once, instant delivery, top-tier AT&T, T-Mobile and Verizon coverage, and — uniquely — the option of a real US phone number. Compatible with any carrier-unlocked eSIM phone, including iPhone 11 and later, Samsung Galaxy S20 and later, and Google Pixel.
