Luxembourg eSIM FAQs
Does an eSIM work in Luxembourg?
Yes — TripSIM eSIMs work across Luxembourg on local 4G/5G networks (POST Luxembourg, Orange Luxembourg, Tango). You activate before you fly and it connects automatically when you land.
Can I keep my UK number while using a Luxembourg eSIM?
Yes. Your physical UK SIM stays active for calls, texts and WhatsApp. The TripSIM eSIM runs alongside it as a data-only line.
Is hotspot / tethering included?
Yes, every TripSIM plan supports personal hotspot.
When should I install the eSIM?
Install before you leave the UK while on WiFi. Activation only starts when you connect to a local network in Luxembourg.
Is TripSIM cheaper than UK carrier roaming in Luxembourg?
Almost always. UK carriers typically charge £3–£6 per MB on UK carriers in Luxembourg. Save up to 80% vs UK roaming.
Will a TripSIM eSIM work across Luxembourg?
Yes. TripSIM connects to POST Luxembourg, Orange Luxembourg, Tango, which together cover Luxembourg City, Esch-sur-Alzette, Vianden and most Luxembourg travel destinations. Coverage in rural areas may be more limited – check the coverage map before travelling off the main routes.
How much data do I need for 2 days in Luxembourg?
For typical UK-tourist use (maps, messaging, social, occasional video calls), 0.5–1 GB per day is a comfortable allowance. We recommend our mid-tier plans for shorter trips and unlimited for two-week stays.
Is the TripSIM Luxembourg eSIM faster than buying a SIM at Luxembourg airport?
Buying a local SIM in Luxembourg usually means queueing at an arrivals kiosk, showing your passport, topping up in Euro and configuring APN settings. A TripSIM eSIM is QR-activated before you fly and online the moment your phone connects to a Luxembourg network.
Can I make voice calls or send SMS with a TripSIM Luxembourg eSIM?
TripSIM is a data-only eSIM. Voice and SMS are not supported – but you can call and message over WhatsApp, FaceTime, Telegram and other internet-based apps as normal. For UK emergency services, your physical SIM remains the appropriate route.
Does the TripSIM Luxembourg eSIM work alongside my UK SIM?
Yes. Dual-SIM phones (iPhone XS and later, most modern Androids) can run your UK number for calls/SMS and your TripSIM data plan in parallel. We recommend turning off mobile data on your UK SIM to avoid roaming charges.
