Coverage & connectivity.
The United States has one of the world's most extensive mobile networks, with three national carriers collectively covering over 99% of the populated land area. T-Mobile leads in 5G reach with mid-band 5G in more than 300 cities. Verizon offers the deepest rural 4G penetration — essential for national park visits and highway road trips. AT&T provides strong coverage in business districts and airport terminals. Interstate highways between major cities maintain consistent 4G/LTE throughout. National parks including Yellowstone, Grand Canyon, and Yosemite have partial coverage on main trails — expect gaps in deep wilderness areas. Hawaii and Alaska are included in coverage but density varies by island and region. Airport data speeds at JFK, LAX, and O'Hare typically exceed 100 Mbps on arrival.
Questions about United States
Is New York City fully covered?
Yes. 4G/LTE and 5G coverage throughout Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. NYC subway stations have growing 4G coverage — above-ground and most stations are connected.
Does this work on cross-country road trips?
Yes. Nationwide roaming with no extra charges. Interstate highways I-10, I-80, and I-90 have solid 4G. Remote stretches through Nevada and Wyoming may briefly drop to 3G.
Can I stream video and use navigation?
Yes. Our unlimited plans support streaming, navigation (Google Maps, Waze), and video calls without throttling restrictions.
Does this work in Hawaii and Alaska?
Yes, both are included. Hawaii has excellent coverage across all major islands. Alaska has 4G in Anchorage, Fairbanks, and major towns; remote areas may be off-grid.
What's the best plan for a 2-week US trip?
Our 10 GB / 30-day plan is ideal for most travelers. If you plan intensive navigation, streaming, or remote work, our unlimited plan gives you flexibility.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of a physical card, you scan a QR code and your plan installs instantly — no SIM tray needed.
Is my phone eSIM-compatible?
iPhone XS (2018) and newer, most Android flagships from 2020+, and all Samsung Galaxy S21+ devices support eSIM. Check our compatibility page for the full device list.
How do I install the eSIM?
After purchase, we email a QR code. On iPhone: Settings → Cellular → Add eSIM → Scan QR Code. On Android: Settings → Network & Internet → SIMs → Add eSIM. The whole process takes under 60 seconds.
Can I keep my regular SIM while using this eSIM?
Yes. Most phones support dual SIM (physical + eSIM). Keep your home number for calls and SMS — use Flysimio for data abroad. You control which SIM handles what in your phone Settings.
Does the eSIM include a hotspot (tethering)?
Yes, all Flysimio plans include mobile hotspot at no extra charge. Share your data connection with laptops, tablets, or other devices freely.
What happens when my data runs out?
You can top up data from your account dashboard at any time. Top-ups are applied instantly — no need to buy a new eSIM or wait.
Can I get a refund?
Yes. We offer a full refund within 14 days of purchase. Contact contact@flysimio.com with your order number.
How long is the eSIM valid for?
You have 6 months from your purchase date to activate the eSIM. Once activated, the plan validity period (e.g., 7 days, 30 days) begins counting down.
Will the eSIM work at the airport when I land?
Yes — as long as you installed the eSIM before your flight, it activates automatically when your phone connects to a local network on landing. No Wi-Fi required for activation.
What if the QR code doesn't scan?
If the QR code won't scan, you can enter the activation code manually — we include both in the email. You can also contact our 24/7 support team and we'll resend or manually provision your eSIM.
