Free eSIM for Luxembourg FAQs by co:sim

Everything you need to know about the free new-user eSIM offer.

Does the free eSIM work when crossing into France, Germany or Belgium?
Yes, automatically. The 1 GB allowance applies identically across all EU33 countries — no roaming indicator + no extra charges when the phone hands off between POST Luxembourg + Orange France.
Can I use it on the free trams and buses?
Yes. Luxembourg’s transit runs mostly above ground + the new tram across Kirchberg + Ville Basse has solid 5G. Mobilitéit.lu app works fine for live departures.
Will it work on the Ardennes / Mullerthal trail network?
Mostly. POST covers main Ardennes towns (Vianden, Clervaux, Wiltz) fully — though deep valleys may briefly drop to EDGE. Mullerthal canyon sections can dip; download Komoot offline.
Do I need a Luxembourgish ID to use the eSIM?
No. The local ID + address rule applies to physical prepaid SIMs sold inside Luxembourg. A roaming eSIM profile only needs your home email.
Who's eligible for the free eSIM?
New users who have not previously claimed a free eSIM. Eligibility is verified at checkout.
Will I be charged anything?
$0 is charged for the free eSIM. A valid card is collected at checkout for verification only — this prevents the same person claiming multiple free eSIMs. You only pay if you choose to top up later.
How long is the free eSIM valid?
Install and activate the eSIM within 30 days after purchase. Once activated, the free plan is valid for 7 days from your first connection. After that, top up anytime to extend the validity — the same eSIM keeps working.
Can I top up or buy more data after?
Yes. Top up the same eSIM with any paid plan at any time — your data and validity extend instantly, no reinstall required. You can also buy plans for any of our 190+ other destinations.
Can I claim the free eSIM again?
No. This free eSIM is a new-user offer, so it can only be claimed once.
How does the free plan compare to paid plans?
Same high-quality network coverage. Paid plans offer more data and longer validity — and you can top up onto your free eSIM at any time.
