Unlimited Internet in Luxembourg: The Connected Traveler's Guide
Unlimited internet in Luxembourg starts at $9.90 with a 3-day travel eSIM: buy it online, install it before you leave and browse without counting gigs from the moment you land, on 4G/5G. Prefer a plan by the gig? Those start at $6.90 (3GB). Either way: no SIM swapping and no store visits.
And now the fact that makes this tiny country special: in Luxembourg you don’t pay a cent to get around. In 2020 it became the first country in the world to make ALL public transport free, trains, buses and trams, for residents and visitors alike. So you move across the whole country for free, and your only “mobility expense” is the data to know which train to catch. Perfect combo. 🐼
Free transport + unlimited internet: the perfect pair
Free transport doesn’t mean guessable transport. To really squeeze it you need live timetables, routes, connections and the map always open. That’s where unlimited internet shines: you check the next train twenty times a day without fearing you’ll run out of gigs right when it leaves in 4 minutes. Navigation open all day, zero guilt.
Land connected from the airport
You land at Luxembourg airport and the magic starts right there: with your eSIM already active, you instantly check which bus or connection drops you downtown (free, of course) text the group that you’ve arrived and follow the ride on the live map. No airport-WiFi hunting, no guessing stops.
How does the Luxembourg eSIM work?
No rocket science: buy online, get a QR code in your inbox, scan it over WiFi before you travel, and the eSIM activates when you land and your phone picks up the local network. Your regular SIM stays untouched, so your WhatsApp stays exactly the same. If your phone is from the last few years (iPhone XS onward and most recent mid-range and flagship Androids) it already supports eSIM.
What to see in Luxembourg (getting around for free)
- The capital: the old town is a World Heritage Site, with the Bock casemates carved into the rock and the Grund district down below, along the river.
- Vianden: a fairy-tale castle above the town, one of Europe’s prettiest. Reachable by public transport. Free, of course.
- The Moselle valley: vineyards and riverside villages on the border with Germany. A perfect half-day plan.
The country is so compact that many travelers cover it all in 2 or 3 days, hopping from train to bus. That’s why the 3-day unlimited plan fits like a glove.
Why unlimited instead of gigs?
Luxembourg is an all-day-outdoors kind of destination: maps, train times, castle photos, the video call to show off the trip, the stories you post on the spot. With an unlimited plan you ration nothing and do zero mental math on megabytes. And on the country’s 4G/5G networks, everything loads in a flash.
| Plan | Best for | Price |
|---|---|---|
| 3GB | A laid-back getaway: maps, messages and the essentials | $6.90 |
| Unlimited 3 days | Full-on trip: browsing without counting gigs, not even once | From $9.90 |
What about roaming? Let’s do the math
Turning on roaming with your home carrier usually costs several dollars a day, or worse, charges you per MB. For a country you can cover in 2 or 3 days, the math just doesn’t work: with the eSIM you get unlimited data from $9.90 for 3 days, pay once and forget about the surprise bill waiting for you back home.
Continuing on to Belgium, France or Germany?
Luxembourg sits right in the heart of Europe: Brussels, Paris and Cologne are just a train ride away (those trains you do pay for 🙂). If your route crosses several countries, a single Europe eSIM is the smarter move: it rides along the whole way with nothing to switch.

Frequently asked questions
Is public transport free for tourists too?
Yes, for everyone, no ticket or sign-up needed: trains, buses and trams across the whole country since 2020. Only first class on trains is paid separately.
Is the unlimited plan really unlimited?
Yes: you browse without counting gigs for the days of your plan. One thing to know: it’s for your phone, plans don’t allow hotspot sharing.
Does the same eSIM work if I also visit Belgium or France?
The Luxembourg eSIM covers Luxembourg. If your route crosses several countries, the Europe eSIM is the better fit: one plan for the whole region.
Is there 5G in Luxembourg?
Yes. The eSIM runs on 4G/5G networks, depending on your area and your phone.
