🎯 Where Luxembourg Online stands apart
Three positioning points relevant for businesses evaluating Luxembourg Online.
🕰️ One of Luxembourg's oldest ISPs
Founded in 1995, Luxembourg Online has a long track record in the local market. For residential and basic office connectivity, this history matters to many customers.
🔗 Independent ISP option
Not tied to the national operator POST or the mobile networks. For businesses that want to separate internet and telephony suppliers, Luxembourg Online is a viable connectivity choice.
⚠️ Not a telephony provider
This is the most important fact on this page. Businesses searching for "Luxembourg Online phone system" or "internet.lu telephony" will not find those products, because they do not exist. For a phone system, pair Luxembourg Online internet with a dedicated Cloud PBX provider.

❓ Common questions
Does Luxembourg Online offer a Cloud PBX or business phone system?
No. Luxembourg Online is an internet service provider. It does not offer Cloud PBX, hosted telephony, SIP trunks, or virtual phone numbers. Businesses that need a phone system must use a separate telephony provider.
Can I use Luxembourg Online internet with a Cloud PBX?
Yes. A Cloud PBX runs over any standard broadband connection. If you use Luxembourg Online for internet access, you can still use any Cloud PBX provider on top of it. The internet connection and the phone system are independent services.
Is Luxembourg Online regulated by the ILR?
Luxembourg Online is regulated as an internet access provider, not as a telephony provider. It does not appear in the ILR's register of authorised voice communication services. For regulated business telephony in Luxembourg, you need a provider with ILR telephony authorisation.
What is the difference between an ISP and a Cloud PBX provider?
An ISP (internet service provider) delivers the internet connection to your premises. A Cloud PBX provider delivers the business phone system that runs over that connection. You need both: an ISP for connectivity and a Cloud PBX provider for telephony. Luxembourg Online is an ISP only.
Why does pbx.lu include Luxembourg Online in the competitor section?
Some businesses in Luxembourg search for "Luxembourg Online phone system" or "internet.lu telephony" when looking for a business phone solution. This page exists to clarify that Luxembourg Online does not offer Cloud PBX services and to point those businesses toward providers that do.
Is Luxembourg Online a good choice for a small business that only needs internet?
Yes. For straightforward broadband connectivity, Luxembourg Online is an established and viable ISP option. The limitation appears only when a business also needs telephony from the same supplier. Pairing Luxembourg Online with a separate Cloud PBX provider works well for many small businesses.
