The 60-second verdict
Flysimio sells 5 GB for 30 days in Luxembourg at $8.50, with access to POST, Orange and Tango. Airalo's cheapest 30-day Luxembourg plan is $69.00, sold as unlimited-only. For a two-day business trip, our 1 GB / 7-day plan at $2.25 is the sensible buy.
Be realistic about Luxembourg though. The country is 2,586 km² and you can drive across it in under an hour. Almost nobody visits Luxembourg alone — it is a stop between Brussels, Trier and Metz, or a business trip. If your travel touches Belgium, France or Germany at all, the Europe regional plan is the better product.

Luxembourg's networks
POST Luxembourg, Orange and Tango serve the country, all with 5G. Luxembourg is small, wealthy and densely covered — national 4G/5G is effectively complete, and there is no meaningful coverage gap for a visitor to plan around.
Free public transport, and what it means
Luxembourg made all public transport free nationwide in 2020 — trains, trams and buses, for everyone including tourists. That is genuinely useful and worth planning around: you do not need ticketing apps or contactless top-ups, so your data use drops to maps and messaging. The tram through Luxembourg City and the trains out to Vianden and Echternach are all covered.
Coverage by destination
- Luxembourg City — 5G across the UNESCO old quarters, the Grund, the Kirchberg EU Quarter and Findel airport.
- Vianden and the castle — well covered.
- Müllerthal ("Little Switzerland") — good on the roads, thinner on the forest trails and rock formations.
- Moselle wine route (Remich, Grevenmacher) — covered.
- Esch-sur-Alzette and the south — 5G.
- Cross-border commutes to Trier, Metz and Arlon — you will switch networks within minutes of leaving.
How much data do you need?
Very little. Luxembourg is tiny, Wi-Fi is everywhere, and public transport is free so there is no ticketing app to run. A few days uses well under 1 GB for most people; 3 GB at $5.75 is more than enough for a fortnight.
Setting it up
- Buy and install on Wi-Fi before you travel.
- Switch the line on at Findel and enable Data Roaming for that line only.
- Turn Data Roaming off on your home line.
- If you are driving in from Belgium, France or Germany, expect to cross a border within the hour — check whether a regional plan suits you better.
- Luxembourg uses the euro and Type F plugs.
Frequently asked questions
What is the best eSIM for Luxembourg?
Flysimio — 5 GB for 30 days is $8.50 with access to POST, Orange and Tango, against $69.00 for Airalo's cheapest 30-day Luxembourg plan, which is unlimited-only. For a short business trip the 1 GB / 7-day plan at $2.25 is usually enough.
Should I buy a Luxembourg eSIM or a Europe eSIM?
Unless you are staying strictly inside Luxembourg, buy the Europe regional plan. The country is small enough to cross in under an hour, and almost every visit touches Belgium, France or Germany — a Luxembourg-only plan stops at the border.
Is public transport really free in Luxembourg?
Yes. Luxembourg made all public transport free nationwide in 2020 — trains, trams and buses, for residents and visitors alike. There is no ticketing app to run, which keeps your data use down to maps and messaging.
How much data do I need for Luxembourg?
Very little — well under 1 GB for a few days for most people. Wi-Fi is widespread and free transport removes the usual app overhead. A 3 GB plan at $5.75 covers a fortnight comfortably.
Do I need an eSIM for Luxembourg if I am from the EU?
Probably not. Luxembourg is an EU member using the euro, so roam-like-at-home allowances from an EU SIM apply in full. Check your existing plan before buying anything.
