5G in Belgium

• With 5G you can surf even faster than today on the existing 4G networks.
• At the same time, you will notice a significant improvement in response time or latency, making the mobile network and applications even more responsive.
• We use growing data volumes (for video, music, gaming, etc.) and a growing number of devices (smartphones, sensors, video cameras …), all of which are connected simultaneously. 5G is the solution that supports an even greater number of devices, without any loss of quality and with greater reliability.
• 5G is also greener as less energy is used to transfer data.

5G stands for "5th Generation". 5G is the name given to the fifth generation of mobile network technology and is the next milestone in the evolution of wireless, after 1G, 2G and 4G.

5G is the successor to 4G (fourth generation), offering much higher speeds and hardly any latency. On 5G, latency does not exceed 1 millisecond, in comparison to up to 50 milliseconds on 4G.

Like previous generations, 5G runs over radio waves sent from antennas. But 5G is transported much more efficiently, calculating the precise amount of radiation needed to be sent towards the desired user.

With your current smartphone you can call and surf the 2G/4G network. You do need a compatible device or your smartphone will not be able to detect the 5G-network

Don't worry: If you have a 5G device but you are in an area without 5G coverage then you can still surf our 2G/4G network.

We are constantly working with suppliers to expand our selection of 5G compatible smartphones as quickly as possible. Go to our website and discover our current range of 5G compatible smartphones.

The launch of 5G does not involve additional CO2 emissions, on the contrary.

As a technology 5G is more energy-efficient than 4G and 2G, allowing for the transfer of more data with the same power consumption and also making the technology more environment-friendly.

Moreover, 100% of Proximus’ electricity supply comes from green energy, such as solar panels and wind turbines.

Self-driving cars, delivery drones, remote surgery… Thanks to its higher speed and a hyperactive network, 5G will revolutionise our lives in the years to come.

In all European countries, 5G is deployed within the framework of the safety standards set by international and independent organizations. As an independent organisation, the opinion of the World Health Organization (WHO) is clear: there is no evidence to suggest that the technology on which 5G is based endangers public health.

5G operates within the same frequency range as existing 2G, 4G and Wi-Fi networks. In the course of the last 30 years, numerous studies on the subject have not been able to establish any negative impact whatsoever.

At Proximus we address these concerns through constant research into new technologies and by keeping our customers informed and advising them on the necessary precautions.

5G allows networks to carry large data volumes more efficiently than 4G.

These are the 5 advantages of 5G:

1. Faster speeds for downloading movies and series or for video chatting on the go.
2. High responsiveness for data-intensive activities, such as cloud gaming or virtual reality.
3. Reliable connections that allow you to stream content from virtually anywhere.
4. More connected devices using a faster signal in the same geographical area, during large events, for example: 4G connects about 4,000 devices per square kilometer versus about 1 million devices with 5G.
5. Low latency to enable drones and self-driving vehicles.

The Internet of Things, which comes down to connecting and adding intelligence to things like cars, sensors and robots, will also benefit from 5G. This technology will facilitate smart cities, connected agriculture, self-driving cars and transport...

In February 2025, Testachats ranked Proximus #1 for mobile coverage in Belgium, with an average score of 34,487 points, ahead of all other operators. These results are based on over 56,000 measurements collected via the BeCover+ app, evaluating browsing, streaming, and daily network stability. Proximus aims for 100% nationwide 5G coverage by 2026.
