eSIM for Luxembourg

eSIM, roaming or a local SIM in Luxembourg

Luxembourg is a founding member of the European Union, so the options depend on where your SIM comes from.

How much data to plan for

Luxembourg has good Wi-Fi in most hotels and cafés, and many visits are short, so data needs are usually modest. Approximate figures:

• Maps and navigation: a few megabytes per hour; handy for finding lifts and stairways between the city's upper and lower town.
• Public transport apps: light; useful for planning bus, tram and train connections.
• Messaging and email: light.
• Video calls: typically several hundred megabytes per hour; a big part of usage for business travellers.
• Social media and photo uploads: moderate to heavy.
• Streaming: heavy, often more than a gigabyte per hour in high definition.

Before you travel

An eSIM needs an internet connection to install, so set it up at home over Wi-Fi. First check your phone supports eSIM and is carrier-unlocked, then follow the install guide for iPhone, Samsung or Pixel.

Label the line "Luxembourg" or "Travel", keep your home SIM as the default for calls and texts, and select the Spidot line for mobile data.

• Install a day or two before departure.
• Keep a screenshot of the QR code email.
• Download offline maps if you plan to hike the Mullerthal Trail or in the Ardennes.
• If you use a non-EU SIM, turn off data roaming on it before you arrive.

Arriving in Luxembourg

Luxembourg Airport, at Findel, is close to the city and the Kirchberg district. Many visitors also arrive by train from Brussels, Paris, Metz, Trier or Koblenz, or simply drive in from a neighbouring country.

When you arrive, select the Spidot line for mobile data and turn on data roaming for that line. Our data roaming guide shows where to find the setting. If the connection does not appear within a couple of minutes, switch flight mode on and off.

Coverage in the city, the valleys and the countryside

In Luxembourg City, Esch-sur-Alzette, Differdange, Ettelbruck, Diekirch and other towns, mobile data generally works well. Main roads and railway lines are usually well covered. Orange provide service on Spidot plans in Luxembourg.

The terrain is hillier than many people expect, and signal can vary in places:

• Luxembourg City's valleys: in the Grund, Clausen and Pfaffenthal districts, deep in the Alzette and Pétrusse valleys, signal can be weaker than up on the plateau.
• The Bock casemates: the underground tunnels block signal; download anything you need before going in.
• The Ardennes: the wooded valleys around Vianden, Clervaux, Esch-sur-Sûre and the Upper Sûre lake can have gaps, particularly on hiking trails.
• Mullerthal: the sandstone gorges and forest paths of the Mullerthal Trail can block signal in places.
• The Moselle: the wine villages along the river are generally covered, but your phone may pick up German networks from the opposite bank.

Data on trains, trams, buses and road trips

Public transport in Luxembourg, including trains, trams and buses, is free for standard second-class travel throughout the country, which makes it easy to explore without a car. Journey planner apps show routes and departures; data lets you use them wherever you are.

Trains link Luxembourg City with Ettelbruck, Clervaux, Esch-sur-Alzette and the borders, while buses serve the Mullerthal, Vianden and the Moselle villages. Mobile data on trains and buses is generally fine for maps, messaging and browsing, with occasional drops in deep valleys and tunnels.

Sharing data with a hotspot

Business travellers often use their phone's personal hotspot to get a laptop online between meetings or on the train. The hotspot uses whichever line is selected for mobile data, so check it is the Spidot line.

Laptops can use a lot of data through updates and cloud syncing. Pause those while tethering, and consider a larger or unlimited plan if you need a hotspot every day.

Using public Wi-Fi safely

Luxembourg offers free Wi-Fi in many public places, as well as in hotels, cafés and on some public transport. It is useful, but shared networks can be insecure, which matters for business travellers handling sensitive information.

• Use your eSIM data for banking, card payments and work logins.
• Confirm the exact network name before connecting.
• Turn off automatic joining of open networks.
• Use your organisation's VPN if it provides one, and keep your devices updated.

Practical tips for Luxembourg

A few local details where a data connection helps:

• Currency and payments: Luxembourg uses the euro, and cards and contactless payments are accepted almost everywhere.
• Languages: Luxembourgish, French and German are all official languages, and English is widely spoken, especially in Luxembourg City. Signs and menus are often in French.
• Getting between levels: Luxembourg City has public lifts and a funicular linking the upper town with the valley districts and Kirchberg. Your map app can show the routes.
• Hiking: the Mullerthal Trail and the Escapardenne trails are well marked, but rocky sections can be slippery after rain. Carry water and a charged phone.
• Opening hours: shops may close earlier than in some countries, and many are closed on Sundays. Check opening times on your phone.
• Schengen: the village where the agreement was signed has a small museum and monument by the Moselle, near the meeting point of Luxembourg, France and Germany.

Luxembourg on a multi-country trip

Luxembourg is often combined with Belgium, France and Germany, and sometimes with the Netherlands as part of a Benelux trip.

For a trip through several countries, a Europe plan covers 36 countries, including Luxembourg, on a single eSIM. Given how close the borders are, it is often the simplest choice, because your phone can connect to any neighbouring network without leaving your plan. If you are only visiting Luxembourg, a Luxembourg plan is the more focused option.
