5G in Luxembourg in 2026: coverage, networks and plans — complete guide
Luxembourg is one of the most advanced countries in Europe for 5G deployment: four operators hold licences granted by the ILR, major cities are broadly covered, and 5G is included at no extra cost in all main plans. Coverage is not uniform across the entire territory, however, and not all networks are equal. This guide explains how 5G works in Luxembourg, compares coverage and speeds by operator (POST, Tango, Orange, Eltrona), and helps you choose the right 5G plan for where you live.

Luxembourg adopted a national 5G strategy as early as 2018, as part of the European action plan for fifth-generation networks. The Grand Duchy set the target of covering all inhabited areas with 5G by 2030, in line with the European connectivity agenda. As of 2026, deployment is well advanced in urban and peri-urban areas, and is continuing in rural zones.
Key milestones in Luxembourg’s 5G rollout
- 2018: Luxembourg government presents the national 5G strategy
- July 2020: The Institut Luxembourgeois de Régulation (ILR) launches 5G frequency auctions (700 MHz and 3,600 MHz bands). Four operators win licences: POST, Orange, Proximus (Tango) and Luxembourg Online. The state receives €41.33 million in fees for 15 years.
- October 2020: POST launches the first commercial 5G services in Luxembourg
- November 2020: Orange launches 5G commercial services
- 2021: Tango deploys its commercial 5G network
- End 2022: contractual target of 50% territory coverage in the 700 MHz band
- End 2024: contractual target of 90% territory coverage in the 700 MHz band

With a commercial launch as early as October 2020 and four licensed operators, Luxembourg is among the pioneer countries in 5G deployment in Europe. Its compact territory (2,586 km²) enables faster deployment compared to larger European countries, resulting in 5G coverage density that is generally above the European average in urbanised areas.
5G frequencies allocated in Luxembourg — what it means for you
Understanding the 5G frequency bands helps interpret the coverage differences between operators. Two main bands were allocated at the ILR auction in July 2020.
The 700 MHz band — the coverage band
The 700 MHz band is the low-frequency 5G band. Its main feature is excellent signal propagation: 700 MHz waves pass more easily through obstacles (buildings, terrain, vegetation) and cover greater distances with fewer antennas. This is the band used to cover rural areas and building interiors.
At the 2020 auction, POST, Orange and Tango each received 2×10 MHz in this band. Luxembourg Online received 10 MHz. The commitment to 90% territory coverage in 700 MHz by end 2024 drives the pace of rural deployment.
The 3,600 MHz band — the performance band
The 3,600 MHz band (3.6 GHz) offers significantly higher speeds than the 700 MHz band, but with a shorter range. This is where the impressive 5G speeds are achieved — potentially exceeding 1 Gbit/s in well-equipped dense areas. This band is primarily deployed in city centres and high-density usage zones.
POST and Orange each received 110 MHz in this band; Tango received 100 MHz; Luxembourg Online only 10 MHz. This spectrum difference partly explains the performance gaps between operators in dense urban areas where both bands are available.
| Band | Range | Speed | Main use | Spectrum allocated (POST / Orange / Tango / LU Online) |
|---|---|---|---|---|
| 700 MHz (n28) | Long range | Moderate | Rural areas, indoors | 2×10 MHz / 2×10 MHz / 2×10 MHz / 10 MHz |
| 3,600 MHz (n78) | Short range | Very high (>1 Gbit/s) | Dense urban areas | 110 MHz / 110 MHz / 100 MHz / 10 MHz |
Source: Luxembourg Government — 5G ILR auction results, July 2020
If you live in a rural area, the 700 MHz band determines whether you have 5G at home. In dense urban areas, your phone often benefits from both bands simultaneously (Dual Connectivity), delivering maximum 5G speeds. Official ILR coverage maps may show your zone as covered, but actual speeds depend on which band is available at your exact address.
5G coverage by operator in Luxembourg: who covers what?
5G coverage data in Luxembourg is published by the ILR and independently measured by services such as nPerf. Here is the operator-by-operator overview as of 2026.
POST — the widest 5G network
POST has the most extensive 5G network in Luxembourg, with dense coverage across the Centre, South, East and West of the country, and coverage reaching the North. According to a 2023 Speedchecker study covering the entire Luxembourg territory across all mobile technologies, POST ranks first for mobile download speed. POST claims 5G population coverage of around 94.8% and received the « Best in Test » Award at the Mobile World Congress 2024 for its mobile network — for the third consecutive year. Maximum theoretical 5G speeds reach 1.5 Gbit/s in the best-equipped areas.
Tango — second position, strong urban density
Tango ranks second in national 5G coverage according to nPerf. The operator has dense coverage in central Luxembourg City and surrounding municipalities, in the South and East. Tango coverage is particularly strong in the border zone with France — an advantage for cross-border workers. The North of Luxembourg is less well covered by Tango 5G than by POST. Cross-border workers will find more details in our guide to cross-border mobile plans in Luxembourg.
Orange — third position, urban-focused coverage
Orange ranks third nationally. Orange 5G coverage is mainly concentrated on the main activity hubs — Luxembourg City and the southern region. Speeds reaching 1 Gbit/s are found in the historic centre and the Gare district of the capital. No 1 Gbit/s readings are seen near the borders or in the North according to nPerf data.
Luxembourg Online — limited 5G network
Luxembourg Online obtained 5G frequencies in the 2020 auction, but its deployment remains limited compared to the three major operators. The operator is primarily focused on the fixed internet market. See our Luxembourg Online mobile guide for more details.
Eltrona — 5G via POST network
Eltrona is a virtual operator (MVNO) using the POST network. Customers therefore benefit from the same 5G coverage as POST — the country’s widest network — in covered areas and with a compatible smartphone. More details in our Eltrona mobile Luxembourg guide.
| Operator | 5G coverage rank | Geographic strengths | Weaknesses | Own network? |
|---|---|---|---|---|
| POST | 🥇 1st | Whole country, including North and rural areas | — | Yes (MNO) |
| Tango | 🥈 2nd | Luxembourg City, South, East, French border | Thinner in rural North | Yes (MNO) |
| Orange | 🥉 3rd | Luxembourg City, southern region | Limited coverage outside dense areas | Yes (MNO) |
| Eltrona | = POST | Same coverage as POST | — | No (MVNO / POST network) |
Sources: nPerf — field measurements · ILR — official coverage maps · POST — official 5G page. Coverage figures evolve with ongoing network deployment.
Official coverage maps are based on theoretical models, not address-by-address field measurements. Two neighbouring streets can have very different coverage levels depending on local topography and building density. Always check your operator’s coverage tool at your exact address — see the section How to check coverage at your address.
5G speeds and network performance in Luxembourg
Geographic coverage is one thing; real-world speeds are another. The following figures are drawn from independent measurements (Speedchecker, nPerf, SpeedGEO) and official operator communications.
POST — speed leader according to independent measurements
POST delivers the best overall performance in independent measurements. According to a 2023 Speedchecker study covering the entire Luxembourg territory, POST ranks first for mobile download speed. Maximum theoretical 5G speeds reach 1.5 Gbit/s in the best-equipped areas, and average mobile download speed (all technologies combined) is around 148 Mbit/s according to SpeedGEO. These results earned POST the « Best in Test » Award at the Mobile World Congress 2024.
Typical real-world 5G speed (dense area, low load): 200–500 Mbit/s
Average 4G speed in Luxembourg: ~30–80 Mbit/s
5G vs 4G real-world gain: ×3 to ×15 depending on area and time of day
Tango — strong performance in dense urban areas
Tango delivers highly competitive 5G speeds in dense urban areas, especially in central Luxembourg City where nPerf data shows a high density of connections reaching 1 Gbit/s. The gap with POST becomes more noticeable outside major agglomerations, where Tango’s network density is lower.
Orange — competitive in city centre
Orange delivers competitive 5G speeds in the areas where its network is deployed, particularly in the historic centre of Luxembourg City and the Gare district. Outside dense areas, Orange’s 5G coverage and speeds are more limited than competitors’.
5G latency: an underappreciated advantage
Beyond speeds, 5G brings a significant advantage in latency — the network response time. 5G latency drops below 10 milliseconds in the best conditions, compared to 20–40 ms on 4G. This gap is noticeable for online gaming, augmented reality, and high-quality video conferencing.
To measure your actual mobile speeds in Luxembourg — 4G or 5G — you can run a test on our speed test tool or on nPerf from your smartphone. Run the test at different times of day for a representative picture.
4G vs 5G in Luxembourg: do you really need it?
5G is included at no extra cost in all main operator plans in Luxembourg. If you’re in a covered area and have a compatible smartphone, you get it automatically. But it’s a legitimate question whether the difference is noticeable in daily use.
4G in Luxembourg
- Near-total territory coverage, including remote rural areas
- Speeds more than sufficient for everyday use (HD streaming, browsing, video calls)
- Compatible with all smartphones since around 2012
- Typical speeds: 20 to 100 Mbit/s download
- Possible congestion in very dense areas at peak hours
5G in Luxembourg
- Significantly higher speeds — up to 10–15× faster than 4G in optimal conditions
- Lower latency (<10 ms) — noticeable for online gaming, augmented reality
- Less congestion — better experience in dense areas
- Included at no extra cost in main plans
- Coverage still incomplete in some rural areas of the North
- Requires a 5G-compatible smartphone (recent models from 2020–2021 onwards)
Downloading a 4K film (50 GB) on 4G (~50 Mbit/s): ~130 minutes
Downloading a 4K film (50 GB) on 5G (~300 Mbit/s): ~22 minutes
Online gaming (latency): 4G ~30 ms vs 5G ~8 ms — noticeable difference in competitive play
5G mobile plans in Luxembourg: how it works
As of 2026, 5G is included at no extra cost in the main plans offered by POST, Tango, Orange and Eltrona (on the POST network). There is no separate « 5G plan » — it’s simply a network technology included in existing offers.
Two cumulative conditions to access 5G
The device must include a 5G modem chip and support the frequency bands n28 (700 MHz) and n78 (3,600 MHz) used in Luxembourg. Mid-range and high-end smartphones launched since 2020–2021 are generally compatible. For iPhones, 5G is available from the iPhone 12 (2020) onwards.
Coverage remains incomplete in some rural areas. Outside 5G zones, the phone automatically switches to 4G or 4G+ with no service interruption.
Operator-specific nuances on 5G
- Tango: GO Mobile S plans get « 5G Fast » — speed is slightly throttled compared to M, L and Unlimited plans. M, L and Unlimited plans get full 5G with no speed limit domestically.
- POST: 5G is included in all POP Mobile plans, with maximum theoretical speeds of 1.5 Gbit/s. Real speeds depend on the plan, area and device.
- Orange: 5G is included in main plans (Access+, BeUnlimited), subject to geographic eligibility and device compatibility.
- Eltrona: 5G is available via the POST network in covered areas, with no additional limitations announced on main plans.

5G adoption observed on Switchr: Among mobile plans subscribed through Switchr in 2026, all are explicitly 5G (5G is now included in all major plans at no extra cost — it is therefore no longer a differentiating criterion). This shift is primarily driven by mobile operators who, with few exceptions, now only offer 5G plans.

See the comparison toolWhich smartphone for 5G in Luxembourg?
To use 5G in Luxembourg, your smartphone must be compatible with the frequency bands used by Luxembourg operators — primarily bands n28 (700 MHz) and n78 (3,600 MHz).
General compatibility rule
In practice, the vast majority of mid-range and high-end smartphones launched since 2020–2021 are 5G-compatible. Recent entry-level models are also often compatible. Models predating 2019 generally are not. For iPhones, 5G is available from the iPhone 12 (2020).
| Brand | 5G compatibility from | Luxembourg bands supported? |
|---|---|---|
| Apple iPhone | iPhone 12 (2020) | Yes (n28 + n78 included) |
| Samsung Galaxy | S20 series (2020) and mid-range A52 5G (2021) | Yes for European models |
| Google Pixel | Pixel 5 (2020) | Yes for EU models |
| OnePlus | OnePlus 8 5G (2020) | Yes for EU models |
| Xiaomi / Redmi | Mi 10 (2020) and Redmi Note 11 Pro 5G (2022) | Check exact model bands |

Be careful with refurbished smartphones or models bought outside the EU: some models sold for other markets (Asia, North America) may not support the n28 and n78 bands used in Luxembourg, even if they are technically « 5G ». Check the exact bands before buying, especially on specialist sites like GSMArena.

How to check 5G coverage at your exact address
5G coverage varies not only by operator, but also by address. Here are the official and independent tools to check your exact situation.
The ILR official tool — the regulatory reference
The Institut Luxembourgeois de Régulation publishes the official coverage maps for all Luxembourg operators, including 5G. These maps are updated four times a year for 5G. The tool allows address-based searches and shows coverage by municipality. Available at web.ilr.lu.
Official operator coverage maps
nPerf — independent field measurements
The nPerf website aggregates real speed measurements from users in the field, giving a picture of effective performance — sometimes different from the official coverage declared by operators. Useful for an idea of real speeds in your neighbourhood.
Coverage maps remain indicative — based on theoretical models (official maps) or aggregated measurements (nPerf). Reality in your specific flat or office can differ: a thick wall, a basement, or a neighbouring building can significantly reduce signal quality. Only a real test on site will confirm the actual coverage.

Which operator has the best 5G network in Luxembourg in 2026?
POST has the most extensive 5G network in Luxembourg, with the widest geographic coverage (including rural areas and the North) and the best overall performance according to independent studies. POST received the « Best in Test » Award at MWC 2024 for its mobile network. Tango ranks second with excellent performance in urban areas and strong coverage on the French border. Orange is in third position with coverage mainly in dense urban areas. Eltrona, as a MVNO on POST’s network, offers the same coverage as POST.
Is 5G available everywhere in Luxembourg?
No. As of 2026, 5G coverage is very good in urban areas (Luxembourg City, Esch-sur-Alzette, Differdange, Dudelange) and along main routes, but remains incomplete in some rural areas of the North. All operators have committed to the ILR to cover 90% of the territory in the 700 MHz band by end 2024. The European target is full coverage of all inhabited areas by 2030. Where 5G is not available, the phone automatically switches to 4G or 4G+ with no service interruption.
Do I need a special plan to get 5G in Luxembourg?
No. As of 2026, 5G is included at no extra cost in the main plans of all Luxembourg operators — POST, Tango, Orange and Eltrona (on POST’s network). There is no separate option or plan to subscribe to. The only requirements are a 5G-compatible smartphone and being in an area covered by your operator’s 5G. If both conditions are met, your phone connects to 5G automatically.
What are the real 5G speeds in Luxembourg?
Maximum theoretical speeds reach 1.5 Gbit/s on POST’s network in the best-equipped areas. In real everyday conditions, 5G speeds typically range between 100 and 500 Mbit/s download — 3 to 15 times faster than average 4G. 5G latency drops below 10 milliseconds in the best conditions. These figures vary by area, simultaneous user load on the antenna, and the device used.
Is my smartphone compatible with 5G in Luxembourg?
Mid-range and high-end smartphones launched since 2020–2021 are generally 5G-compatible. For iPhones, 5G is available from the iPhone 12. Models predating 2019 are generally not compatible. Check that your device supports 5G bands n28 (700 MHz) and n78 (3,600 MHz) in its technical specifications — on the manufacturer’s website or on GSMArena. A non-5G smartphone will continue to work perfectly on 4G.
Does 5G work abroad with a Luxembourg plan?
When roaming in the European Union, you use your Luxembourg plan’s data at no extra charge (the « Roam Like at Home » regulation). However, access to 5G while roaming depends on the roaming agreement between your Luxembourg operator and the local foreign operator — it is not automatically guaranteed. In practice, you often use 4G when roaming even if your plan includes 5G. For everything related to data abroad, see our complete guide to roaming in Luxembourg.
What is the difference between the 700 MHz and 3,600 MHz bands for 5G?
The 700 MHz band (n28) offers better range and building penetration but more limited speeds — used to cover rural areas. The 3,600 MHz band (n78) offers very high speeds (up to 1 Gbit/s and above) but shorter range — deployed mainly in dense urban areas. Your smartphone automatically uses the optimal available combination depending on your location. In cities, it often benefits from both bands simultaneously (Dual Connectivity) to maximise speeds.
