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 $3.28 per gigabyte in the United States. That's $0.0032 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 192 countries — that's the shape of the invoice, 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 ($3.28/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days | $9.84 | $25–50 | $30–60 + ID and paperwork |
| 1 week | $22.96 | $50–100 | $40–70 + 30-day cap |
| 2 weeks | $45.92 | $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 $0.0032/MB.
- No auto-renewal you forgot to cancel. Balance runs out, the eSIM stops.
It's not a marketing gimmick — it's an engineering decision born from indifference to gimmicks. You can't make a tariff cheaper than no fine-print and no expiry — so we don't.
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
