Luxembourg is a country the size of a city region, and that shapes the trip. You land at Findel, you are in the Unesco old town in 20 minutes, and by the afternoon you can be standing under Vianden castle or walking a sandstone gorge in the Mullerthal. Most visits mix the capital with the Moselle wine villages, the Ardennes in the north, and often a border hop to Trier, Metz or Bastogne.
A FairSIM eSIM roams onto Tango, POST or Orange, the three networks that cover the Grand Duchy. Coverage is dense because the country is small: 5G in Luxembourg City and the larger towns, 4G everywhere else, with the usual dead spots deep in the river valleys. You install the eSIM before you fly, keep your home number for calls and bank codes, and share the connection by hotspot if you travel with a laptop or a second phone. Four plan sizes are on sale for Luxembourg, and the app shows current prices from the live catalogue.
The local rule worth knowing: since 29 February 2020 public transport across the whole country is free. Buses, trams and second-class train travel inside Luxembourg cost nothing, and so do the Pfaffenthal panoramic lift and the funicular. You still need a ticket for first class and for any leg that crosses the border. That means your data goes on timetables and maps rather than on ticket apps, and Mobiliteit.lu is the one app to install before you arrive.
Wholesale rates in US dollars, with nothing added at checkout. Buy in the FairSIM app and the plan is on your phone in seconds.

Speed policy shown in the app
Typical speed: Luxembourg is one of the better connected small markets in Europe, with all three networks running 5G. Expect fast mobile data in the capital, and solid 4G in the Ardennes and along the Moselle.
The country is only about 2,586 km², so coverage is dense: the capital, Esch-Belval, the airport, the motorways and the Moselle route are all well served. Signal thins in the deep valleys around Vianden, Esch-sur-Sûre and parts of the Mullerthal gorges, and disappears inside the Bock Casemates tunnels.
It depends on how you travel. Find your trip below, then pick the plan that matches. You can always top up in the app.
Two or three nights in the old town, Kirchberg and Grund.
Why data matters: Maps in the layered old town, Mobiliteit.lu for bus and tram times, museum bookings, restaurant reservations and photos uploading from the Corniche.
EU institutions, banks and funds, usually midweek.
Why data matters: Teams and Zoom on the move, hotspot for the laptop between meetings, and mail syncing on the tram out to the European Court.
Echternach, the Mullerthal Trail, Vianden and Esch-sur-Sûre.
Why data matters: Komoot or GPX tracks, weather radar, train and bus times back to the capital, and offline maps for the gorges where signal drops.
Remich to Schengen by bike, boat or car, with cellar visits.
Why data matters: Booking tastings, translating labels, checking opening hours, and calling a taxi when you have tasted too much to drive.
Luxembourg with Trier, Metz, Brussels or the Belgian Ardennes.
Why data matters: Navigation and tolls across three borders. A single-country plan stops working once you cross, so a Europe regional plan usually fits better.
Daily roaming passes look small until you multiply them by the length of the trip. FairSIM plans for Luxembourg start at $4.99 and never bill per day.
Luxembourg sits inside the EU roaming area, so EU and most UK plans are cheap or included. US and Australian daily passes are where the real money goes.
| Carrier | Roaming charge | FairSIM |
|---|---|---|
| AT&T International Day Pass (US) | $12 per day per line, $6 for additional lines | from $4.99, no daily fee |
| Verizon TravelPass (US) | $12 per day, high-speed data then slowed | from $4.99, no daily fee |

On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.
Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.
Install the eSIM at home over Wi-Fi, then switch the line on and enable data roaming when you land at Findel.
Public transport is free countrywide in second class. Use Mobiliteit.lu for times, and buy a ticket only for first class or a cross-border leg.
A Luxembourg plan stops working the moment you cross into Germany, France or Belgium. If Trier, Metz or Bastogne are on the list, take the Europe regional plan instead.
Download offline maps for the Mullerthal gorges, the Our valley near Vianden and the Upper Sûre before you set off; signal drops between the cliffs.
Keep your home SIM active for bank SMS and voice, with its own data roaming switched off so it cannot bill you.
Most shops close on Sundays and many close early on Saturday; plan groceries and pharmacy runs on Friday or Saturday morning.
Cards are accepted almost everywhere, but small bakeries, market stalls and some rural cafés still prefer cash euros.
If you drive in winter, winter tyres are required in wintry road conditions, and speed cameras on the motorways are unforgiving.
There is no Uber or Bolt ride-hailing in Luxembourg, so plan around free public transport and Webtaxi. Because buses, trams and second-class trains are free, you do not need a ticket app at all unless you travel first class or cross the border.
Free Wi-Fi is easy to find in Luxembourg: the airport, hotels, cafés, museums, many CFL trains and city-run hotspots in the capital all offer it. Quality is uneven. Café networks are fine for maps and messages but slow at peak hours, hotspots often drop when you walk between them, and several ask you to accept terms again every session, which breaks navigation halfway up a staircase in the Grund. Treat Wi-Fi as a bonus for big downloads in the hotel, and let the eSIM handle the day.
POST, Tango and Orange all sell prepaid starter packs, and you will find their shops in Luxembourg City around the Gare and the city centre, in Belval and in the larger shopping centres. Retail at Findel airport is small and hours follow flight times, so do not count on buying a SIM at 10pm. Bring your passport: prepaid lines in Luxembourg are registered to an identified holder, and the shop will ask for ID before the SIM is activated.
A local prepaid pack makes sense if you are staying for months and want a Luxembourg number for deliveries, doctors or a local bank. For a weekend in the capital, a hiking week in the Mullerthal or a business trip to Kirchberg, a travel eSIM is simpler: you install it at home over Wi-Fi, it roams on the same Tango, POST and Orange towers, you keep your own number live for calls and bank codes, and there is no shop visit or ID form. FairSIM plans are data-only, so calls and texts go through WhatsApp, FaceTime or your home SIM.
Yes. Any unlocked eSIM-capable phone connects to Tango, POST or Orange. On iPhone that means XS, XR or newer; most recent Pixel, Samsung Galaxy S and Motorola flagships also support eSIM.
Tango, POST or Orange. The app shows which network a plan uses, and your phone may switch between them if the plan allows it.
Yes. All three networks run 5G, best in Luxembourg City and the main towns, with 4G LTE as the fallback across the countryside. Your handset needs 5G support to use it.
No. A Luxembourg plan covers Luxembourg only, which matters here because borders are 20 minutes away. For Trier, Metz, Brussels or the Belgian Ardennes, buy the Europe regional plan.
Yes. Every FairSIM plan supports hotspot, with no separate cap, so a laptop or a travel companion can share the line.
Install it before you fly, over home Wi-Fi. Turn the line and data roaming on after you land. Validity typically starts at the first connection to a Luxembourg network.
Yes, since 29 February 2020. Buses, trams and second-class trains inside Luxembourg are free, as are the Pfaffenthal lift and the funicular. First class and cross-border legs still need a ticket.
A city weekend usually runs 1 to 3 GB. A week of sightseeing and hiking with maps and photo uploads sits around 5 GB. Work trips with video calls and hotspot use go higher, so 10 GB or unlimited is safer.
A local POST, Tango or Orange prepaid SIM needs a shop visit and ID, and gives you a Luxembourg number that is useful for a long stay. For a short trip, an eSIM roams on the same networks, installs before departure, and keeps your own number reachable.
A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.
FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer, on iOS 17.4 or later for the one-tap install with no QR code. iPhones bought in mainland China do not support eSIM at all, even when unlocked. Not sure yours is unlocked? Check Settings, General, About, Carrier Lock, or ask your carrier. The full list is on the How it works page.
Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.
No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
Plans from $4.99. Install before you fly, track your data live, and top up in seconds if you need more.
