The fastest network in Belgium: Proximus, the 5G leader
Proximus puts mobile performance at the heart of its strategy. Thanks to continuous investments in cutting-edge mobile technologies, we offer the fastest 5G network with outstanding reliability, meeting the needs of even the most demanding users.
The January 2026 SpeedChecker study shows that Proximus stands out in Belgium with the highest download speeds on the market across all technologies: 4G and 5G. These results are based on hundreds of thousands of tests carried out by real users and therefore reflect the actual everyday speed.
This makes the Proximus network the ideal choice for streaming, gaming, remote working and sharing large files.
The best mobile network in Belgium is at Proximus
A good network is not only about speed: it must also deliver a smooth and stable mobile experience every single day.
The 2026 MedUX study recognises the Proximus network as offering the best mobile experience in Belgium. This award is based on an advanced “Quality of Experience (QoE)” methodology, which goes beyond purely technical indicators to measure what the end user really feels.
The MedUX method combines:
- technical indicators such as connection speed, response time, stability and signal quality
- user-centred indicators: smooth web browsing, videos without stuttering, lag-free gaming, uninterrupted cloud downloads, and more
These automated tests, carried out across several geographical areas, are used to calculate an overall QoE score. In this respect, Proximus stands out as the network offering the best mobile experience in Belgium, with an optimal combination of speed, stability and perceived quality.
The Proximus network: the best mobile coverage
A good network is useless if you cannot access it wherever you are. Proximus therefore invests heavily to ensure wide and consistent mobile coverage.
The January 2026 SpeedChecker study confirms that Proximus has the mobile network with the best coverage in Belgium, based on real-life tests carried out in various urban and suburban areas.
Proximus, a trusted operator
Our results are built to last, thanks to sustained investments in 5G roll-out and network modernisation. Numerous independent studies have already rewarded the strong performance of Proximus, confirming a long-standing track record of excellence:
- In 2024, BIPT had already confirmed that the Proximus network was the fastest in Belgium, both in 4G and 5G, with the best mobile coverage.
- The Test Achats study from February 2025 ranked Proximus number one for mobile coverage in Belgium. This result is based on thousands of measurements carried out via the BeCover+ app, assessing browsing, streaming and network stability in everyday situations.
- The OpenSignal report from March 2025 highlights that Proximus provides a consistently high-quality mobile experience, whether at home, on the move or when working remotely, with excellent service consistency (81.8%) and network availability of 97.9%. OpenSignal also shows that Proximus customers enjoy an excellent mobile download experience, topping the national ranking.
These results, together with the recent MedUX and SpeedChecker awards, show that Proximus has been considered one of the best networks and mobile operators in Belgium for many years, further strengthening the trust of the millions of customers who already choose us.
