The GO Fibre Multigiga range: structure and tiers
Tango calls its internet range GO Fibre — or more precisely GO Fibre Multigiga, reflecting the multi-gigabit speeds on most tiers. All offers use FTTH technology with symmetric speeds. The standard commitment is 24 months. Installation and cabling fees are waived from the S tier.
GO Fibre S — 1 Gbit/s entry-level
Tango’s entry-level tier with 1 Gbit/s symmetric speeds and a Wi-Fi 6 router. Sufficient for 1–2 person households with typical usage: browsing, HD streaming, video calls, light remote working. Includes: landline, Kidjo Stories and Mangas.io.
GO Fibre M — 2 Gbit/s with Wi-Fi 7 ⭐
Tango’s flagship tier. At 2 Gbit/s with Wi-Fi 7, it combines connectivity power and cutting-edge wireless technology. Wi-Fi 7 brings reduced latency, better handling of many simultaneous devices, more stable connection at distance from the router and optimised energy consumption. The preferred choice for 2–4 person households, intensive remote workers, gamers and families. This is where Tango concentrates its most aggressive promotions.
GO Fibre L — 5 Gbit/s for large households
With 5 Gbit/s and Wi-Fi 7, sized for large households with many simultaneous users or intensive bandwidth needs.
GO Fibre XL — 8.5 Gbit/s for power users
Tango’s ultra-premium tier. At 8.5 Gbit/s with Wi-Fi 7, this is the maximum speed on the Luxembourg market — for the most demanding power users.
4G@Home from the day after subscription. All GO Fibre plans include a 4G SIM card enabling connectivity from day one, without waiting for fibre installation. A real advantage for house moves or new arrivals in Luxembourg.
Included in all GO Fibre plans: a landline for receiving calls, access to Kidjo Stories (stories for children aged 2–10) and Mangas.io (manga for 14+), and Perplexity Pro access for a limited time. Fixed Communications Packs are available as add-ons for outgoing calls.

GO Duo: Tango’s internet + TV bundle
GO Duo is Tango’s bundled offer combining fibre internet and television.
GO Duo tiers differ from GO Fibre. GO Duo M offers 1 Gbit/s (Wi-Fi 6), GO Duo L offers 2 Gbit/s (Wi-Fi 7) and GO Duo XL offers 5 Gbit/s (Wi-Fi 7). The number of TV channels also varies: approximately 80 channels on M, and 130+ on L and XL.
Up to 200h cloud recording
GO Duo L/XL include up to 200 hours of cloud recording — less than POST (400h) but well above Orange (~50h). Unlimited replay on compatible channels.
Premium sport — a key differentiator
Tango is the only Luxembourg consumer operator to include access to major European football competitions: the full UEFA Champions League on Pickx+ Sports, the Premier League and top Bundesliga fixtures on Play Sports — included in the Sport bouquet on L and XL tiers.

Compare offers →Network and performance
Tango operates on POST Technologies’ fibre network via fibre unbundling (regulated access imposed by the ILR). This architecture allows Tango to offer speeds identical to POST while maintaining its own active network equipment.
Real-world performance — among the market’s best
According to independent nPerf 2025 measurements, Tango is among the three operators with the best real-world FTTH speeds in Luxembourg — alongside POST and Orange. Use our speed test to check performance in your area.
5G mobile network — no. 2 in Luxembourg
Tango is Luxembourg’s second mobile operator in terms of 5G coverage and subscribers. Its 5G network is particularly dense in Luxembourg City and major towns.
No-penalty cancellation for international relocation
If you need to leave Luxembourg during your commitment period, Tango allows cancellation of your GO Fibre contract without penalty on simple presentation of a foreign address proof. Key protection for expats in Luxembourg.
Fibre network = POST infrastructure. Tango does not own its own fibre network — it uses POST Technologies’ network via ILR-regulated unbundling. Raw fibre performance is comparable to POST, with differences in active equipment (routers, servers) and customer service.
Tango fibre coverage in Luxembourg
Fibre coverage from Tango is available across Luxembourg’s 12 cantons. In practice, Tango’s coverage is more urban than POST’s — which serves all municipalities without exception. Check your exact address eligibility with our fibre eligibility tool before subscribing.
Not eligible for Tango fibre? If your address isn’t covered in FTTH, Tango offers a 4G@Home no-commitment router as an alternative.
Coverage is address-level, not municipality-level. Even within a covered municipality, Tango fibre may not be available at your exact address. Always test eligibility before committing.
Customer service
24/7 chat — the digital approach
Tango’s primary support channel is 24/7 chat via the MyTango app. Works well for digitally comfortable customers who prefer avoiding phone queues. Less suited to those who prefer phone or in-person service.
~20 shops — the country’s second retail network
Tango has around twenty retail locations — the second physical distribution network after POST (115+). Less extensive than POST but far more accessible than Orange or Luxembourg Online.
Service in 5 languages
Available in French, English, German, Luxembourgish and Portuguese.
Considering switching internet provider to Tango? Number portability is free and the transition is generally smooth.

If I leave Tango before the end of my 24-month contract, how much will I actually have to pay?
This question comes up regularly on Switchr support, particularly in cases of unexpected moves or loss of income. Tango’s contractual rule: the remaining monthly payments until the end of the commitment period are due, with a reduction applied during the second half of the contract (LU consumer rule — see ILR). In practice, among Switchr users who report an early termination, the average penalty observed is €125 — to be weighed against the potential savings if you switch to a more competitive offer. The calculation depends mainly on the number of remaining instalments and current available offers.
