The trip you booked vs. the trip you took
You came for three nights in Budapest — Buda hill, Széchenyi baths, ruin bars in District VII. You ended up extending: a day in Eger for the cellars, a side trip to Lake Balaton, a long afternoon in Pécs because the train was cheap. That's the actual Hungary trip. The Budapest itinerary is the brochure version of it.
Roamzy charges $1.43 per gigabyte in Hungary. That's $0.0014 per megabyte, billed in real time as your phone uses data on Hungarian networks. No subscription, no expiry, no minimum bundle. One per-MB rate across 192 countries — same rate in District VIII as in Eger or on the road south to Pécs.
How much will Roamzy actually cost on this trip?
A typical Hungary day burns around 1 GB: Maps for Pest's tram routes and the regional rail, the camera-translator on a Magyar menu (English is uneven outside the tourist core), your bank app for a card payment that's contactless almost everywhere, video calls home. Call it 1 GB/day:
| Trip length | Roamzy ($1.43/GB) | Tourist roaming pass | Airport local SIM |
|---|---|---|---|
| 3 days | $4.30 | $15–40 | $10–25 + paperwork |
| 1 week | $10.00 | $25–55 | $15–30 + paperwork |
| 2 weeks | $20.00 | $35–95 (often two passes) | $20–35 + 30-day cap |
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.
A SIM at Budapest-Ferenc Liszt is sold from the standard kiosks: passport, KYC, a tourist tariff, and a queue you didn't budget for after a 03:00 Wizz Air landing. The eSIM is already attached when you taxi to the gate; the meter starts on Hungarian networks.
Where does Roamzy work in this country?
- Budapest — 5G across the city, dense LTE, working signal in metros M1–M4 (occasional drops on M2 cuts)
- Debrecen, Szeged, Pécs, Győr, Miskolc — solid LTE in the centers, 5G in the cores
- The motorway network (M1, M3, M5, M7) — continuous LTE
- Lake Balaton north and south shores — strong 4G in resort towns, thinning on the back roads
- Puszta and Hortobágy — patchy 4G; offline maps for the open plain
Hungary is geographically uncomplicated for connectivity — flat country, small distances, dense network. Outside the eastern plains and a few wine-region back roads, you stay attached.
How do I install my Roamzy eSIM?
| Plug type | Voltage | Frequency | iOS | Android |
|---|---|---|---|---|
| Type C, F | 230 V | 50 Hz | iPhone XS+ | Pixel 3+, Galaxy S20+ |
- Sign in to Roamzy via Telegram or Google
- Top up 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 BUD
Hungary uses HUF, not EUR — most tourist-area card terminals accept Visa/Mastercard, but conversion rates are usually better in HUF than DCC ("Pay in your currency?" — say no). 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 the second top-up. The rate on top-up #1 is the rate on top-up #20.
- No fine-print throttling. One rate, full speed — first GB and the hundredth both cost $0.0014/MB.
- No auto-renewal. Balance runs out, the eSIM stops. No background charge surfacing months later.
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 continues to other countries?
Hungary is a hub for Central European travel. The eSIM hands over the moment you cross:
- Romania — by car through Oradea or by train through Lőkösháza
- Slovenia — common onward via Zalaegerszeg or a short flight
- If you want the underlying mechanics — how roaming actually gets priced and why it hurts
