Networks & coverage in United States
Your Flylo eSIM connects to United States's leading mobile networks, with speeds up to 5G where available:
- Verizon2G / 4G / 5G
- AT&T4G / 5G
Coverage is strong and consistent across cities, suburbs and the main interstate highways, with 5G widely available in major urban areas. Signal can weaken or disappear in remote regions — the desert Southwest, mountain areas and the backcountry of national parks — where any network struggles.
Staying connected in United States
The United States is one of the easiest places in the world to stay connected, and your Flylo eSIM runs on Verizon and AT&T — two of the country's largest networks, reaching up to 5G where it has been rolled out. In cities and suburbs you'll rarely think about signal: coverage across metros such as New York, Los Angeles, Chicago, Miami and San Francisco is dense, and 5G is widely available in major urban areas. The interstate highways and the corridors between big cities are well served too, which matters if you're planning a road trip.
The thing worth planning for is the sheer scale of the country. The US has vast, thinly populated stretches — the deserts of the Southwest, high mountain passes, and the backcountry of national parks such as Yellowstone, Yosemite and the Grand Canyon — where any network can thin out or drop entirely. This isn't specific to eSIMs; it's true of every phone, including one on a local contract. Download offline maps and any booking confirmations before you head somewhere remote, and don't count on a live signal deep inside a park.
Because the eSIM has access to more than one network, your phone can latch onto whichever carrier is available in a given area, which helps on longer drives. For everyday use — navigation, ride-hailing, messaging, streaming and uploading photos — it behaves just like a local line, without you swapping out your home SIM. Set it up before you fly, switch it on when you land, and you'll have data from the moment you clear the airport.
Setting up your United States eSIM
Install the eSIM before you fly, then set it as your data line when you land. Travel eSIMs connect as a roaming line even on local US networks, so make sure Data Roaming is switched ON for the Flylo eSIM or it won't pick up data.
How much data will you need?
As a rough guide, five days of maps, messaging and social media is around 3-5 GB, with heavier video streaming using considerably more. Estimate your trip with our data calculator →

FAQs about eSIMs for United States
Does a Flylo eSIM work in the United States?
Yes. Any eSIM-compatible, unlocked phone can connect. The eSIM runs on Verizon and AT&T, reaching up to 5G in areas where 5G has been rolled out, so it works just like a local line for data.
How good is coverage away from the cities and in national parks?
Coverage is strong across cities, suburbs and the main interstate highways. In remote areas — the desert Southwest, mountains and the backcountry of parks such as Yellowstone or the Grand Canyon — any network can weaken or drop out, so download offline maps before heading off-grid. This applies to all phones, not just eSIMs.
Does the eSIM come with a US phone number?
No. It's a data-only eSIM, so there's no US number for regular calls or texts. You can still call and message over the internet using apps like WhatsApp, FaceTime, iMessage or your usual data-based services.
Can I use it as a hotspot to tether other devices?
Yes. You can share the connection with a laptop, tablet or another phone via personal hotspot or tethering, just as you would at home.
It's unlimited data — does anything change if I use a lot?
You can use it freely for everyday browsing, maps, streaming and calls. As with most unlimited plans, speeds may be eased back after a fair-use threshold within a given period, but your connection isn't cut off.
Do I need to turn Data Roaming on?
Yes. Travel eSIMs connect as a roaming line even though you're on local US networks, so Data Roaming must be switched on for the Flylo eSIM line or it won't receive data. This setting only affects the eSIM, not your home SIM.
Can I keep my normal SIM in the phone at the same time?
Yes. The eSIM sits alongside your existing SIM, so you can keep your home number active for calls and texts while using the Flylo eSIM for data across the US.
Are eSIMs available in United States?
Yes. Flylo eSIMs work across United States on the strongest local 4G/5G carriers, with automatic network fallover so you stay online in cities, airports, on trains, and in rural stretches.

How do I activate an eSIM in United States instantly?

Does Flylo eSIM in United States support 5G?
