Luxembourg Mobile Plans Comparator

In short — In 2026 in Luxembourg, the two most competitive operators are Tango and Orange: the best all-round plan is Tango GO Mobile M (20 GB + data rollover, €21/month, no commitment), and Orange leads on price — cheapest is Orange Access+ (€6.99/month, 3 GB), most data Orange Boom (100 GB, €22.99/month), cheapest unlimited Orange BeUnlimited (€39.99/month); for US/Canada travellers, POST POP Mobile MAXI.

In July 2026, mobile plans in Luxembourg range from €6.99/month (Orange Access+, 3 GB) to €65/month (POST POP Mobile MAXI, unlimited in Luxembourg + 110 GB in Europe and unlimited USA/Canada calls). The mid-range sweet spot (20–30 GB) sits between €21 and €35/month. For comparable services, price gaps between operators can exceed 60% according to our Switchr analysis — unlimited plans with USA roaming range from €40 (Orange BeUnlimited) to €65/month (POST POP MAXI). By choosing the right plan for your profile, you can save up to €25/month, or more than €300 per year.

In July 2026, Tango and Orange stand out as the most competitive operators. Tango leads on innovation and flexibility (100% no-contract, data rollover, Data Boost). Orange responds with aggressive pricing (Boom, BeUnlimited). POST dominates on 5G network quality (nationwide coverage, up to 1.5 Gbit/s) and international premium plans. Luxembourg Online is the only credible alternative for unlimited no-contract at €45/month.

Mid-range (15–25 GB/month): Tango GO Mobile M (€21/month) — 20 GB + data rollover, no contract, strong value in its class.

Large data allowance, contained price: Orange Boom (€22.99/month) — 100 GB covering Luxembourg, Europe and the United States, no contract.

Heavy data user / unlimited: Orange BeUnlimited (€39.99/month) — unlimited data LU+EU+USA, no contract.

International traveller: POST POP Mobile MAXI (€65/month) — unlimited data in Luxembourg + 110 GB in Europe and unlimited calls to the USA and Canada, 5G 1.5 Gbit/s.

Tight budget: POST POP Mobile XS (€8/month, 3 GB) or Orange Access+ (€6.99/month, 3 GB) for a simple Luxembourg number.

Choosing the right mobile plan in Luxembourg goes beyond price and data volume. Four key criteria matter: included calls and SMS, data volume, roaming conditions, and contract commitment. A seemingly cheaper plan can cost more if calls are billed per minute or if data is insufficient for your usage patterns.

Conditions to check before subscribing

Fair use: Even "unlimited data" plans can apply a reasonable-use policy. Check the tariff brochure to see whether reduced speeds kick in beyond a certain monthly volume.

5G speed: Not every operator offers the same 5G speed. POST is the only one to guarantee a minimum 5G speed of up to 1.5 Gbit/s on its premium plans. Orange and Tango offer 5G but without a guaranteed maximum speed.

Included options: POST offers phone insurance at €2/month. Tango offers Data Boost (double your data allowance once a year). These options can represent significant added value.

Data is the single biggest factor influencing mobile plan pricing. In 2026, mid-range plans (15–25 GB) are the most suitable for the majority of Luxembourg users. Wi-Fi is widely available in professional and residential environments, reducing effective data consumption. Cross-border workers and frequent travellers need more EU roaming data.

Tango's data rollover: a concrete advantage. If your GO Mobile M includes 20 GB/month and you only use 14 GB in January, the remaining 6 GB automatically carry over to February — giving you 26 GB that month. This feature eliminates waste and adapts to your real consumption patterns. Unique to Tango in Luxembourg.

On top of rollover, Tango offers Data Boost: the option to double your data allowance once a year. On a GO Mobile L (30 GB), that means 60 GB available for one month — ideal before a long trip or during a high-usage period.

In 2026, Orange and Tango offer their entire mobile range without any contract commitment. Luxembourg Online is also fully no-contract. POST is the only major operator still requiring a commitment period. No-contract plans are ideal for expats, cross-border workers, and anyone whose professional or personal situation may change.

Why choose a no-contract plan? Flexibility is essential for newcomers to Luxembourg, cross-border workers whose professional situation may change, or simply to take advantage of the best deals on the market without waiting for a commitment to end. In 2026, Tango and Orange offer no-contract plans that are just as competitive — if not more so — than their competitors' contract plans.

Over 220,000 cross-border workers commute daily into Luxembourg from France, Belgium and Germany. For these profiles, a suitable mobile plan needs unlimited EU calls, sufficient EU roaming data (at least 20–30 GB), and ideally no contract commitment. For expats travelling to the USA or Asia, POST and Tango Unlimited Extra plans are options worth considering.

Key criteria for a cross-border worker

1. Unlimited calls in Luxembourg and your country of residence. You make professional calls from France, Belgium or Germany using your Luxembourg number. POST (LU+EU calls included), Orange (unlimited) and Tango (unlimited EU calls/SMS) all cover this need.

2. Sufficient EU roaming data. The EU "Roam Like at Home" regulation lets you use your Luxembourg data across the entire EEA at the same rate. Plan for at least 15–25 GB/month if you regularly work from your country of residence without professional Wi-Fi access.

3. No contract commitment. A cross-border worker's situation can change: new employer, relocation. A no-contract plan (Tango, Orange) provides the flexibility you need.

Should you keep your French, Belgian or German plan? No, not if you work regularly in Luxembourg. A foreign number can deter professional contacts and complicate certain procedures (opening a bank account, flat hunting, dealing with the administration). A Luxembourg number is a strong signal of local integration.

By 2026, 5G covers virtually the entire Luxembourg territory. POST has the most extensive network with speeds up to 1.5 Gbit/s on its premium plans. Orange and Tango offer good 5G coverage in urban areas and major transport corridors. All modern mobile plans include 5G by default — although speeds may be capped depending on the plan chosen.

How to get 5G in Luxembourg: (1) A 5G-compatible smartphone (all modern devices from 2022+ qualify). (2) A 5G plan — all current plans include 5G by default. POST explicitly guarantees minimum 5G speeds by plan tier (500 Mbit/s for XS, S, M and L, and up to 1.5 Gbit/s for XL and MAXI). (3) Being in a 5G coverage zone — check operator maps or nPerf.

The concrete benefits of 5G: speeds up to 10× faster than 4G (up to 20 Gbit/s in theory), latency cut to under 1 ms (vs 20–30 ms on 4G), and improved stability in dense areas (city centres, events, transport). For everyday use (streaming, browsing) 4G is often enough — 5G makes the difference for 4K streaming, heavy downloads and cloud gaming.

Switching mobile operator in Luxembourg takes 1 to 3 business days. Your new operator handles number portability entirely. The potential saving is significant: for comparable service, the most expensive offer in a category can cost up to twice the price of the cheapest. There has never been a better time to compare.

1. Check your current contract: commitment end date (if with POST), notice period (typically 1 month), early termination fees.
2. Identify services linked to your number: online banking, two-factor authentication, apps. If you keep your number (portability), these services continue working automatically.
3. Compare plans on Switchr.lu based on your actual consumption profile.
4. Subscribe with your new operator stating you want to keep your number. Provide ID and proof of address.
5. Wait for portability (1–3 business days). Keep your old SIM in your phone until transfer day, then swap to the new one.

You can save up to €100 a year by switching to an equivalent plan. Take advantage of welcome promotions (free months, free activation) reserved for new customers.

→ Full guide: switching mobile operator in Luxembourg · Number portability in Luxembourg

Number portability lets you keep your Luxembourg phone number when switching operator. The process takes 1 to 3 business days and is fully managed by your new operator. Expect a brief service interruption on transfer day.

How it works: when subscribing with your new operator, simply state you want to keep your current number. The new operator contacts the old one and manages the transfer. You receive your new SIM by post or in-store, and get an SMS with the exact transfer date and time.

On transfer day: keep your old SIM in your phone until the scheduled time. You'll experience a brief interruption (minutes to a few hours). Then swap the SIM. Your number is immediately active on the new network.

Porting a foreign number? It is not possible to port a non-Luxembourg number to a Luxembourg operator. You'll need a new Luxembourg number and progressively migrate your contacts and linked services.

All three networks sell a prepaid card: Tango Prepaid (the GO card, the most used in the country, with built-in monthly data packs), POST TipTop (sets from €5 to €100, credit bonus on every top-up, DATA15 pack via SMS to 64000) and Orange Hello (€5-€30 top-ups, data bonus, USA included in the roaming zone). Since the law of 7 June 2017, ID registration is mandatory when buying a card with a Luxembourg number.

Prepaid or no-contract plan?

Prepaid is unbeatable for a short stay, a child or a budget controlled to the cent: no contract, no direct debit, top up whenever you want. But as soon as you stay more than a few weeks in Luxembourg, a no-contract plan almost always works out cheaper: Tango GO Mobile S (€16/month, 6 GB, 5G, cancel anytime) or Orange Access+ (€6.99/month, 3 GB) give you more data and included calls for the same cost or less than a regularly topped-up card — with no risk of being cut off out of credit.

Our take: prepaid to test the network or as a stopgap, no-contract plan for any regular use. The Luxembourg market makes the choice easy: unlike France or Germany, almost every plan (Tango, Orange, Luxembourg Online, Eltrona) is already contract-free — only POST requires 12 months.

The European "Roam Like at Home" rule (EU Regulation 2022/612, guaranteed until 2032) covers 32 countries: your plan's calls, texts and data work across the EU/EEA at no extra cost, within the fair use limit. Outside the EU, data surcharges are automatically capped at €50 with an alert SMS on arrival. Watch out: Switzerland is not covered by RLAH.

What to check before you travel

1. The roaming data cap (fair use). An EU formula sets how much data you can use at the domestic rate — on very cheap plans, the roaming allowance can be lower than the domestic one. Operators show it in each offer's details (the "EU roaming" column in our comparator). 2. Special zones. Orange includes the USA in several plans (Boom, BeUnlimited) — unique in Luxembourg. POST relies on more than 600 roaming partners worldwide with its non-EU packs. 3. Cross-border workers cross the border twice a day: fair use is calibrated for that case — see our cross-border section.

For a long stay outside the EU (United States, Asia…), compare your operator's roaming pack with a local travel eSIM — often cheaper beyond a few GB. And to understand the technology, see the eSIM section.

POST, Tango and Orange all offer eSIM: the operator profile downloads onto the phone's built-in chip, usually by scanning a QR code — no physical card, no waiting for the post. Compatibility: iPhone since the XR (2018), Samsung Galaxy since the S20 (2020), Google Pixel since the 3.

The use cases that matter

Two lines on one phone. Physical SIM for the main number, eSIM for the work line (or vice versa) — the most common set-up in Luxembourg, especially among cross-border workers keeping a number from their home country. Instant activation. Subscribe online in the morning, number active within the hour. Travel outside the EU. A local data eSIM combines with your Luxembourg number, which stays reachable.

Compatibility traps: iPhones sold in mainland China do not support eSIM; some Galaxy models sold in the US, Korea or Hong Kong don't either — check the exact model with the operator. US-sold iPhone 14+ are the opposite: eSIM-only, with no SIM tray.

The comparator above has built-in profile filters: one click applies the right budget and data volume. In July 2026, our presets recommend Tango GO Mobile M (20 GB, 5G, €21/month, no contract) as the best balance, Orange Boom (100 GB, €22.99/month) for heavy users and Eltrona Mobile 2 GB (€5.99/month) as the floor price.
