Luxembourg eSIM

100 Luxembourg plans · from $2.35

Luxembourg City is a fortress town built over two gorges, and the country around it is small enough to cross in under an hour — which is how you end up in Germany, France or Belgium by accident. It is also the only country in the world with free public transport nationwide, so what you actually need data for is the border, not the bus.

Landing at Findel (LUX)

The airport is 6km from the centre and the bus in is free, like every train, tram and bus in the country. Public transport has been fare-free nationwide since 2020 — you simply board.

Which networks you'll be on in Luxembourg

Siima eSIMs for Luxembourg ride POST Luxembourg, Orange and Tango. The country is tiny and comprehensively covered, with 5G across the city and the Kirchberg plateau.

Coverage around Luxembourg

Old town and the casemates

Strong signal across the UNESCO old quarter, the Chemin de la Corniche and the Grund below. The casemates tunnels through the rock lose it — they are a fortress interior, after all.

Kirchberg and the EU institutions

Comprehensive coverage across the plateau, the tram line and the institutional buildings.

Müllerthal and the Ardennes

The hiking trails in "Little Switzerland" and the castles at Vianden and Clervaux are covered on the main routes, with dips in the rock gorges.

The borders

Trier, Metz and Arlon are each within about 45 minutes, and your Luxembourg plan stops at each frontier. This is the single most likely way to lose coverage here.

How much data you need

A couple of days in Luxembourg is 1 GB. It is a small, well-connected country and the transport is free, so there is not much to plan around.

Frequently asked questions

Is public transport really free in Luxembourg?
Yes — since 2020 all buses, trams and second-class trains are fare-free nationwide for everyone, residents and visitors alike. First-class rail and cross-border journeys still require a ticket.
Does a Luxembourg eSIM cover Germany, France or Belgium?
No. All three are within an hour and a day trip across a border is routine here, so a Europe regional plan is usually the more sensible buy for anyone not staying strictly inside the country.
How do I set up an eSIM before arriving in Luxembourg?
Install it at home while you still have Wi-Fi: open Settings → Cellular → Add eSIM and scan the QR code from your Siima confirmation email. Leave the line switched off until you land — the plan starts counting from first use in Luxembourg, not from purchase.
How much data do I need for a trip to Luxembourg?
A couple of days in Luxembourg is 1 GB. It is a small, well-connected country and the transport is free, so there is not much to plan around.
Is an eSIM cheaper than roaming in Luxembourg?
Almost always. Daily roaming passes from most home carriers run $10–15 per day, while Siima plans covering Luxembourg start from $2.35 for the whole trip. You also avoid per-megabyte charges if you exceed a roaming pass allowance.
