What a Luxcom eSIM costs
The cheapest published plan on the Luxembourg travel eSIM is $4.00 for 1 GB valid 7 days. A 2 GB / 15 day plan is $6.50, a 3 GB / 30 day plan is $7.20, and a 5 GB / 30 day plan is $10.35. Larger buckets go up to 20 GB for 30 days at $25.08. Unlimited data is listed separately on the same product, from $10.35 for 3 days. The 3 day unlimited plan at $10.35 costs the same as 5 GB for 30 days, so read the two together before you pick.
Network
The plan is sold under the operator name Luxcom and the supported country is Luxembourg. The product page publishes the speed as 5G. That is the figure to plan around, and real speed still depends on the mast, the handset, and the carrier Fair Usage Policy. Luxembourg is covered as one country on this plan, including Luxembourg City, Esch-sur-Alzette, and the Moselle wine road. The country is only about 2,586 square kilometres, so a single day of driving crosses it more than once. It is not an EU-wide plan. It does not cover Belgium, France, or Germany, so a day trip to Metz, Trier, or Arlon needs its own plan.
How much data you actually need
Maps, chat, and boarding passes sit inside 1 GB for a short stay, and a weekend break will not use much more. Photos and short video push a week toward 3 GB. A longer stay with hotel Wi-Fi plus mobile backup is the 5 GB or 10 GB / 30 day plan. Hotspot use burns the allowance faster than the phone alone.
Unlimited data
Unlimited plans are listed on the same product page, from $10.35 for 3 days, $17.10 for 5 days, $22.95 for 7 days, $28.90 for 10 days, $40.80 for 15 days and $58.65 for 30 days. Unlimited still sits under a Fair Usage Policy, so a hotspot left on all day can be slowed. For a three-day stay the $10.35 unlimited plan is the sensible pick, and for a week or more the 20 GB / 30 day plan at $25.08 covers most trips for less.
Dual SIM
Keep your home SIM for calls and bank texts. Turn on data roaming only for the Luxcom line. iPhone: Settings, Mobile Data, pick the travel line. Android: Settings, Network, SIMs, set mobile data to the travel eSIM. Do this before you leave the airport Wi-Fi.
Arrival and transit
Most visitors land at Luxembourg Airport (LUX) at Findel, about six kilometres from the city centre, and many arrive by train from Brussels, Paris, or Trier. Install the eSIM on hotel or home Wi-Fi before you travel, then switch the data line on after you clear arrivals. You do not need a local shop or a passport photo for this plan.
Install
- Buy the plan and open the QR code in the order email while you still have Wi-Fi.
- On the phone, add an eSIM and scan that code. Label the line “Luxembourg”.
- After landing, set mobile data to that line and leave your home number on for texts.
Phone compatibility
The phone must be carrier-unlocked and eSIM-capable. iPhone XS and later, and recent Samsung Galaxy and Google Pixel models, qualify. A locked handset will not take the QR code. Check the lock status with your home carrier before you pay.
FAQ
Q1: How much is the cheapest Luxembourg eSIM?
$4.00 for 1 GB, valid 7 days, on the Luxcom plan.
Q2: Which operator is on the plan?
Luxcom. The supported country is Luxembourg.
Q3: Does it include calls and SMS?
No. It is a data plan. Keep your home SIM for calls and one-time passwords.
Q4: Is it 5G?
Yes. The product page lists the speed as 5G. Real speed still depends on coverage and the Fair Usage Policy.
Q5: Can I install it after I land?
Yes, if you can reach Wi-Fi. Installing before the flight is simpler, because the QR download needs a connection.
Q6: Will it work outside Luxembourg?
No. This plan is for Luxembourg and it is not an EU-wide plan, so buy a separate one for Belgium, France, or Germany.
Q7: Is there an unlimited option?
Yes. Unlimited plans are listed separately on the same product page, from $10.35 for 3 days.
Q8: Can I share it as a hotspot?
Yes, within the data allowance. Hotspot traffic counts against the same gigabytes, and heavy sharing can hit the Fair Usage Policy.
Q9: What if the QR code fails?
Use the manual activation code in the same email. The phone still has to be unlocked.
Q10: When were these prices checked?
October 2026, against the published variation prices on travelydata.com.
Bottom line
For a short stay in Luxembourg, the $4.00 / 1 GB Luxcom plan is the one to start with. Step up to 5 GB or 20 GB for a longer visit with mobile backup. The published speed is 5G, and unlimited is available from $10.35 for 3 days.
