The two-day Luxembourg trip
A typical Luxembourg trip is short and dense. Land at Findel after a regional connection, train into the city or take a cab to Kirchberg, do a half-day meeting at one of the European institutions or a fund-services office, eat at the Plateau, sleep, second meeting in the morning, fly out. Slack, email, the Court of Justice's filing portal, two video calls back to the home office — none of which survives a queue at a SIM counter you don't have time to find.
Roamzy charges $0.61 per gigabyte in Luxembourg, billed in real time at $0.0006 per megabyte. No subscription. No expiry on the unused balance. No "5 GB for 30 days" pre-buy. One per-MB rate across 193 countries — that's how the bill gets written, not a marketing line.
How much will Roamzy actually cost on this trip?
The business pattern in Luxembourg runs heavy: ride-hail or train from Findel to Kirchberg, the CFL app for the free public-transport network (yes, free since 2020), Slack and Teams all day, two or three video calls back to London or New York, contactless payments in every bistro on Rue Vauban. Stream video at the hotel; in the city, plan on 1–1.5 GB/day:
| Trip length | Roamzy ($0.61/GB) | Tourist roaming pass | Local SIM at Findel |
|---|---|---|---|
| 2 days (single meeting) | $1.23 | $15–35 | $10–25 + 20–30 min at the counter |
| 5 days (full cycle) | $3.07 | $30–80 | $20–40 + KYC with passport |
| 2 weeks (project) | $8.60 | $70–160 (often two passes) | $30–55 + 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.
The Luxembourg airport SIM kiosk is decent but slow at the post-flight peak; on a two-day trip a half-hour wait is half-hour you can't bill the project. The eSIM is on the network from the gate.
What changes if I'm here to work, not tourism?
Hotel Wi-Fi at the Sofitel Kirchberg or Le Royal handles a video call most of the time. At peak it doesn't. That's the kind of detail you learn during a screen-share, not before the trip.
The Luxembourg public-transport network is genuinely free for everyone — bus, tram, and CFL train — and most institution buildings are walking distance from the Pfaffenthal funicular. You'll use less ride-hail than you'd expect. The eSIM keeps the calendar, the map, and the calling-app working as you walk between Cloche d'Or and the Plateau.
How does coverage span the country?
Luxembourg is small and densely covered:
- Luxembourg City (Ville Haute, Kirchberg, Gare, Cloche d'Or) — 5G at 95%+, multiple operators competing on quality
- Esch-sur-Alzette and the south — solid LTE, 5G in central districts
- The Moselle wine country (Remich, Schengen) — continuous 4G/LTE on the asphalt
- The Ardennes north (Vianden, Clervaux) — 4G in the towns, brief drops in the deeper river valleys
- The Findel airport — 5G across the terminal, eSIM attached on the jet bridge
- The CFL trains — near-continuous LTE; brief drops in the longer tunnels
How do I install my Roamzy eSIM?

What are Roamzy's honest limitations?
Business travelers historically lose money to three things, and Roamzy doesn't close those traps — they don't exist in the product.
- 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 during a Zoom call. One rate, full speed — first GB and the hundredth cost the same $0.0006/MB.
- No auto-renewal you forgot to cancel that hits expense reports next quarter. Balance runs out, the eSIM stops.
No bundle to size for a two-day trip, no leftover data to mourn on the flight home. Pricing Luxembourg by the megabyte was an engineering call, and engineering has no budget for fine print.
What if my trip extends across Europe?
Luxembourg sits at a tri-border. Most extensions cross within the day:
- Belgium — Brussels in two hours by train, the eSIM hands over at the border
- France — Metz and the TGV to Paris, same per-MB billing model
- Germany — Trier in 45 minutes by car
