Mobile networks are continuously evolving. Older technologies such as 2G and 3G are gradually being replaced by more modern networks such as 4G and 5G. These offer higher speeds, better reliability, more efficient use of radio spectrum and lower energy consumption.
3G fully switched off since July 2025
In Belgium, 3G networks have been fully switched off since July 2025. This transition went smoothly, demonstrating that the vast majority of users are already using devices compatible with 4G and 5G.
The successful phase-out of 3G is part of a broader evolution in which mobile operators are modernising their networks to meet current and future user needs.
Why will 2G also be phased out?
Following 3G, 2G will also be phased out over time. This technology was originally developed for voice and SMS, but it increasingly falls short of current requirements in terms of efficiency and capacity.
By phasing out 2G, mobile operators can:
- reuse valuable radio spectrum for 4G and 5G;
- improve the quality and capacity of modern networks;
- manage their networks more efficiently in terms of energy and costs.
Why is 2G still active for now?
Unlike 3G, 2G remains operational for the time being.
This is because 2G is still used today by:
- basic mobile phones;
- a large number of machine-to-machine and IoT applications, such as alarm systems, elevators, parking systems, smart meters and other devices requiring only limited data communication.
What does this mean for users?
Consumers with a recent smartphone (4G/5G):
- Nothing will change.
These devices will continue to function fully after the phase-out of 2G.
Users of devices that only support 2G:
- These devices will no longer be able to connect to mobile networks in the future.
Without an upgrade or replacement, they will stop working once 2G is switched off.
When will 2G be phased out?
The phase-out of 2G in Belgium is planned for the period 2028–2030.
The exact timing may differ per mobile operator and may evolve depending on market conditions and coordination between operators and the regulator.
BIPT is closely monitoring this evolution and ensures that users and sectors are informed in a timely manner.
How can you prepare?
BIPT recommends that you:
- check whether your device or application still depends on 2G;
- contact your mobile operator or supplier for information on alternatives (such as 4G/5G devices or specific IoT solutions);
- plan your migration in advance, for example by replacing outdated devices, adapting contracts or configurations, and organising any necessary technical adjustments to avoid service disruptions.
