The Luxembourg Mobile Operators

Post Luxemburg

In addition to conventional mail and finance services, Post Luxemburg also offers fixed-line and mobile communications to its customers. For its mobile services, the former incumbent took over the mobile network LuxGSM in 2013. With approx. 450.000 mobile customers (estimation by connect), this operator is the mobile market leader in Luxembourg. The company operates GSM 900/1800, 3G, 4G/4G+ and 5G mobile networks. It claims to reach 98.8% of the population with 4G and 97% with 4G+. About 10% of the Luxemburg population can already use the 5G service of Post.


Tango is a subsidiary of Proximus, formerly Belgacom, which offers fixed-line and mobile communications in Luxembourg. On an international scale, the company cooperates with Vodafone. Tango states to have 276.000 mobile subscribers, which makes it the number two on this marketplace in terms of subscriber numbers. Tango offers GSM 900/1800, 3G and 4G/4G+ to its customers and has also started deploying 5G in the country. The company claims to cover 97% of the population with 4G/4G+.


Orange Luxembourg is a subsidiary of Orange Belgium and offers fixed-line and mobile communications to its customers. The company only publishes customer numbers for the combined markets of Belgium and Luxemburg (where its total customer base recently surpassed 5 million) but estimates to have a 15 percent market share in mobile communications within Luxembourg. This would roughly correspond to a customer count of 134.000 mobile subscribers. Orange Luxembourg operates GSM 900/1800, 3G, 4G/4G+ and has also started to deploy 5G. Orange claims to reach 97% of the population with 4G.

In the HD Video Class, where the samples have to reach at least 5 Mbps, Post manifests is lead, slightly ahead of Tango, with Orange following. The decision is ultimately made in the UHD video class: Post achieves the highest count of samples with at least 20 Mbps, with Tango following. Here, Orange falls distinctly behind, which costs valuable points.


In the Latency category, Post again takes the lead, ahead of Tango and, at a more distinct distance, Orange.
