What is the best eSIM for Luxembourg?
+
For travellers who want Luxembourgish mobile data on the phone they already own, eSIMbundle is a strong option. Buy a Luxembourg bundle before departure, land at Findel, and use Google Maps, mobiliteit.lu, CFL, Bolt and WhatsApp straight away. A VPN is included with every plan.
Which mobile network does eSIMbundle use in Luxembourg?
+
Your eSIMbundle eSIM connects automatically to an available Luxembourgish partner network when you land, so you do not pick a carrier at the airport. Luxembourg is served by a small number of national operators; the specific one you end up on can vary by location and time.
Does eSIMbundle have good coverage across Luxembourg?
+
Coverage is generally comfortable across Luxembourg City, Esch-sur-Alzette, Vianden, Echternach and Clervaux and along the whole CFL network. Signal can weaken deep in the Mullerthal, in some Our and Sûre valley bends and inside long road tunnels.
Is 5G available with a Luxembourg eSIM, and how fast is it?
+
4G is broadly available across Luxembourg and 5G is generally strong across Luxembourg City and other larger centres. Whether your phone connects on 4G or 5G in a specific spot depends on your device, the available partner network and live local conditions.
How much data do I need for 7, 15 or 30 days in Luxembourg?
+
Light users on Maps and messaging often manage on 1–3 GB a week. Normal travellers using CFL, ride apps, translation, streaming and hotel bookings usually want 5–10 GB a week. Heavy video or hotspot users can push past 20 GB a week. Use the Travel Data Calculator to size a Luxembourg plan for your trip.
Does a Luxembourg eSIM include a Luxembourgish phone number, calls or SMS?
+
eSIMbundle Luxembourg plans are data plans. Use mobile data for WhatsApp, FaceTime and other internet-based calling and messaging. Keep your normal SIM active for calls, SMS and verification messages, subject to your home carrier's roaming charges and support.
Can I keep my normal SIM, phone number and WhatsApp?
+
Yes. On a compatible dual-SIM phone, keep your normal SIM installed and use your eSIMbundle eSIM for mobile data. Your normal phone number stays with your home SIM, and WhatsApp continues using the number already registered to your account.
Can I add more data while I am in Luxembourg?
+
Yes. Sign in to your eSIMbundle account and add another Luxembourg data bundle whenever you need more. The new bundle activates on the same eSIM already installed on your phone — no new QR code, no reinstall.
Should I buy my Luxembourg eSIM before travelling?
+
Yes. Buy your bundle and install the eSIMbundle eSIM before departure while you have a stable internet connection. Then arrive at Findel, turn off airplane mode and you are online — no shop detour and no roaming charges to worry about.
Does eSIMbundle include a VPN in Luxembourg?
+
Yes. A VPN is included with every eSIMbundle plan at no extra cost. Switch it on in the app for a more private connection on Luxembourgish mobile data and on airport, hotel and café Wi-Fi.
Can I use the same eSIM on my next trip elsewhere?
+
Yes. Your eSIMbundle eSIM stays installed on your phone. When you travel to another supported destination, add a bundle for it in your account and it activates on the same eSIM — no new installation required.
