698 of these 1580 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 1580 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for Luxembourg: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for Luxembourg is Horizon eSIM with 1 GB for 7 Days at $0.28. That is $0.28 per GB, the best rate of the 1580 plans we compare from 58 providers. 1057 plans include 5G. 594 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for Luxembourg?
There is no single best eSIM for Luxembourg, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 1580 plans on the numbers, as they stand on 17 October 2026:
- Best value overall Horizon eSIM, 1 GB for 7 Days at $0.28. That is $0.28 per GB, the lowest real rate of every Luxembourg plan we track.
- Best for a long stay Yatelo, 20 GB for 30 Days at $6.99, $0.35 per GB. The best rate among plans that last 30 days or more.
- Highest daily cap on an unlimited plan ByteSIM, 30 Days at $78.90, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and Horizon eSIM did not pay to be named here.
Which mobile networks does Luxembourg have?
Coverage is excellent for a small country. Operators committed to reaching 90 percent of the territory with 5G by 2025, and by 2026 5G covers virtually the whole country, led by POST at 94.8 percent of the population per ILR data.
- POST Telecom: The state owned incumbent, formerly LUXGSM. It runs the country's largest 5G network, reaching 94.8 percent of the population according to regulator ILR data.
- Tango: Owned by Belgium's Proximus, Tango ranks second for 5G reach with dense coverage in the capital and the south and east.
- Orange Luxembourg: Formerly VOXmobile and now part of Orange Belgium, with 5G focused on Luxembourg City and the southern region.
The main MVNO, Join Experience, closed in May 2020 after merging into POST. Luxembourg Online sells LOL Mobile plans and markets itself as an independent operator.
The eSIM plans we compare on this page connect to:
The list above is Luxembourg's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in Luxembourg?
Commercial 5G arrived in October 2020, with POST first, Proximus's Tango the same month and Orange in November. All current mainstream plans now include 5G by default.
How much data do you need in Luxembourg?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Luxembourg right now:
Are unlimited eSIMs for Luxembourg really unlimited?
Not always. 718 of the 1580 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 36 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For Luxembourg the caps we can see published are 0.3 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $0.28 per GB from Horizon eSIM, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in Luxembourg?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for Luxembourg starts at $0.20 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Luxembourg eSIM
Pick the plan, not the brandThe cheapest rate in Luxembourg today is $0.28 per GB from Horizon eSIM, against a median of $1.25. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in Luxembourg is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to Orange, POST, Tango. Expect 5G where the network reaches, 4G everywhere else.
Know what happens when it runs out594 of the 1580 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is ASIMGO at $2.39.
Good to know before you land in Luxembourg
Luxembourg is an EU member, so EU roam like home applies. Cross border day trips to France, Belgium and Germany, which are routine here, stay inside the EU roaming zone, so one EU plan covers the whole visit.
Luxembourg Airport at Findel is the country's only international airport and the usual arrival point for overseas visitors.
Any EU plan or eSIM works across Luxembourg and its neighbours at home rates. If you want 5G, make sure your device supports it; the plans themselves already include it.
Luxembourg Travel eSIM FAQ
Everything you need to know about using an eSIM in Luxembourg
What is the cheapest eSIM for Luxembourg?
Right now the cheapest option ranked by price per GB is Horizon eSIM with 1 GB for 7 Days at $0.28. That works out to $0.28 per GB. Prices change often, so the table above is re-sorted at every price check.
Which is the best eSIM for Luxembourg?
It depends on the trip, so we rank rather than pick a favourite. On today's prices the best value for Luxembourg is Horizon eSIM at $0.28 per GB, the lowest real rate of the 1580 plans we compare. For heavy daily use there are 718 unlimited plans, most with a daily fair use cap, and they only win if you genuinely burn several GB a day. Every pick on this page is the first row of a sort on live prices. No provider can pay to be named best.
Is eSIM available in Luxembourg?
Yes. We track 1580 prepaid travel eSIM plans from 58 providers that work in Luxembourg, roaming onto Orange, POST, Tango. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Which networks will my eSIM connect to in Luxembourg?
The plans we compare connect to Orange, POST, Tango. The exact network depends on the plan you pick. Check the plan details before you buy if one network matters to you.
Do Luxembourg eSIMs support 5G?
1057 of the 1580 plans we track for Luxembourg include 5G where the local network offers it. The rest run on 4G, which is still fine for maps, calls over apps, and video.
Can I buy a Luxembourg eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in Luxembourg. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my Luxembourg eSIM if I run out?
Yes. 594 of the 1580 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Is an eSIM cheaper than a local SIM card in Luxembourg?
For a trip of days or weeks, usually yes. Data for Luxembourg starts at $0.20 for 100 MB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does a Luxembourg eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
How many GB do I need for a week in Luxembourg?
Around 3 to 5 GB covers a week of maps, messaging, and normal browsing. Heavy video or hotspot use needs 1 to 2 GB per day. Today the cheapest plan with at least 5 GB is ASIMGO at $2.39.
Which Luxembourg eSIM gives the most data per day?
Of the plans sold as unlimited here, ByteSIM allows the most at full speed, 10 GB a day from $4.90. The smallest allowance on this page is 300 MB a day, from 4 sellers. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
