We want to offer the best possible experience for all users. By working efficiently, we can increase operational synergies and manage our network in a sustainable way. By collaborating with fixed network, mobile, and deployment companies, we can work simultaneously and get more done faster in a cost-efficient way.

Our fiber partners


Fiberklaar, our Flemish fiber joint venture with EQT Infrastructure, works to design, build, maintain, and upgrade the fiber network across the region to accelerate super fast and stable fiber connectivity in Flanders. Fiberklaar’s target is to connect 1.5 homes and businesses in Flanders by 2028.


Similar to our partnership with EQT Infrastructure, Unifiber is helping us to roll-out the fiber network in Wallonia. This joint venture aims to connect at least 500,000 homes and businesses in Wallonia by 2028.

Glasfaser OstBelgien

In September 2022, we set up a JV called “Glasfaser Ostbelgien” or GO Fiber, a public-private partnership with the German-speaking Community and Ethias. Its objective is to connect almost all of the 40.000 homes and businesses in this region, including in the so-called “white zones”.

Our mobile network partners


MWingz, our joint venture with Orange Belgium, was launched in April 2020 to enable wider outdoor coverage, deeper indoor coverage, and a faster 5G roll-out.

It allows us to reduce each operator’s network footprint by 35% while improving the coverage of the shared network as the number of mobile sites of the shared network will be around 20% higher compared to each operator’s former standalone network.


Since October 2020 we have partnered with Ericsson to build the 5G network of the future with new-generation equipment to guarantee the stability and quality of mobile connectivity as mobile data usage increases.
