Two weeks, three states, one rate
A standard US trip looks like this: fly into JFK, four nights in Manhattan, a domestic to LAX, two nights in LA, an Uber to a rental, four days driving up the Pacific Coast Highway to San Francisco. Three carriers' worth of "service area" if you bought local. With Roamzy: one eSIM, one rate, no carrier swap when you cross from Nevada into California.
Roamzy charges $2.25 per gigabyte in the United States. That's $0.0022 per megabyte, billed in real time as your phone uses data on US networks. No subscription. No expiry on the unused balance. No minimum bundle. One per-MB rate across 193 countries — that's the meter doing its job, not a marketing line.
How much will Roamzy actually cost on this trip?
A typical US visitor uses 1–2 GB per day: Maps for 50-mile drives between things, Uber and Lyft in cities, DoorDash for hotel-room dinner, Apple Pay at every coffee shop, the Delta or United app for rebookings, photos uploading to iCloud. Cars eat data. Call it 1 GB/day for the math, knowing road days run higher:
| Trip length | Roamzy ($2.25/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days | $6.76 | $25–50 | $30–60 + ID and paperwork |
| 1 week | $15.77 | $50–100 | $40–70 + 30-day cap |
| 2 weeks | $31.54 | $80–180 (often two passes) | $50–100 + paperwork |
Competitor prices in columns 3 and 4 are 2025 ranges based on typical offerings; exact figures depend on your home carrier and the airport store you visit. Roamzy's rate in column 2 is our actual published rate from the pricing page.
Tourist SIMs in the US are aimed at a domestic prepaid market — sold at airport kiosks at marked-up prices, often with US ID requirements that confuse foreign travelers. The eSIM bypasses that whole layer.
What changes inside the country
The US is not a single network. Coverage shifts noticeably across the country. The shape of it:
- Major cities (NYC, LA, Chicago, SF, Miami, Boston, Seattle) — 5G dense, throughput stable, indoor coverage solid
- Highway corridors (I-95, I-5, I-10) — continuous LTE between cities, 5G near urban approaches
- National parks (Yellowstone, Yosemite, Grand Canyon, Joshua Tree) — patchy or nothing inside the park boundaries; signal returns at the gates
- The rural West (Wyoming, Montana, Nevada) — long stretches with weak or no signal; offline maps mandatory
- NYC subway and DC Metro — modern stations are wired; older tunnel sections drop briefly
- Hawaii and Alaska — covered in cities and tourist zones, weaker on outer islands and the Alaska interior
If your route includes back-country driving, download maps in advance. That's not a Roamzy issue — that's American geography.
Why is per-megabyte pricing simpler than packages?
A US trip already brings cognitive load: tip math, sales tax that isn't on the sticker, miles and Fahrenheit, a power outlet that's a different shape than home. Connectivity should be the part that just works.
Roamzy is built around that. No first-purchase promo to lure you, then jacked rates. No fine-print throttling — "5 GB at full speed, then 128 kbps." No auto-renewal six months later. One rate, billed by the megabyte, balance carries.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|
| Type A, B | 120 V | 60 Hz | iPhone XS+ | Pixel 3+, Galaxy S20+ |
- Sign in to Roamzy via Telegram or Google
- Top up the eSIM with a minimum of 20 USDT — stablecoins, no cards, no banks, no FX surcharges
- The QR code appears in the dashboard once payment confirms
- Settings → Cellular → Add eSIM → scan QR
- The counter starts the moment you land at JFK, LAX, ORD, MIA, SFO, or any other gateway
Bring a 120 V adapter if you're coming from the EU, UK, or anywhere outside North America. Supported stablecoins, networks, and common iPhone/Android setup errors are in the FAQ.
What are Roamzy's honest limitations?
Three traps Roamzy doesn't have because they were never built in.
- No welcome promo that bait-and-switches your second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling that surfaces on a Yosemite photo upload. One rate, full speed — first GB and the hundredth cost the same $0.0022/MB.
- No auto-renewal you forgot to cancel. Balance runs out, the eSIM stops.
No asterisks, no expiry, no launch campaign. Data in the USA is metered this way because that's how the engineering works, and a tariff with nothing hidden can't be quietly beaten.
What if my trip extends across the continent?
North American trips often cross borders. Same Roamzy account, same logic — the meter just starts billing at the new country's rate:
- Canada — drive across at Niagara or Vancouver, separate country rate
- Mexico — fly into Cancún or drive south from California
