2G networks shutdown

What is the reason for the 2G shutdown?

Mobile networks are evolving rapidly. In 2025, the 3G networks were shut down. Now, the time has come to phase out the 2G network as well.

2G, which has been around for more than 30 years, was originally developed for voice calls and text messages. Today, mobile calls and data traffic mainly use more modern 4G and 5G networks.

By shutting down 2G, operators can:

• free up capacity for 4G and 5G;
• provide faster and more reliable mobile services;
• manage their networks in a more energy-efficient way;
• replace outdated technology with more secure networks.

In other European countries, 2G will be phased out as well.

When will the 2G network be shut down?

The Belgian mobile network operators plan to initiate the shutdown of their 2G networks between 2028 and 2029. The exact dates will be announced at later stage.

Each operator will determine its exact shutdown schedule and will inform their customers in a timely manner.

What devices could be affected?

Due to the wide variety of devices, drawing up a complete list of all devices involved it is not possible. 

It is also important to know that some 4G and 5G devices may be affected by the 2G shutdown if they do not support voice or emergency calls over the 4G network (VoLTE). Network operators will inform the public more in detail when the actual shutdown draws closer.

In addition to classic mobile phones, the following devices may be affected if they are not 4G or 5G compatible:

• old and new 2G-only mobile phones,
• personal alarm systems,
• alarm systems,
• elevators with emergency call systems,
• card payment terminals,
• certain medical devices (e.g. remote monitoring devices), 
• machine-to-machine (M2M) applications,
• other Internet of Things (IoT) applications,
• certain vehicles with eCall (emergency call) systems,
• etc.

After the 2G network shutdown, it may no longer be possible to call, text, or connect over the mobile network using these devices.

How can I prepare for the 2G shutdown?

1. Check your mobile phone

Do you use a device that supports 2G networks exclusively? In that case, calling or texting using the mobile network will no longer be possible after the 2G shutdown.

Do you have a 4G/5G smartphone? Keep an eye on your operator's website when the shutdown approaches for information about whether your device supports voice and emergency calls over 4G or 5G. Older devices, but also more recent models may experience problems when they still depend on the 2G network for voice or emergency calls. After the shutdown, those types of calls will no longer be possible. 

Make sure you enable “Voice over LTE” (VoLTE, 4G network calling) in your device’s settings. Your network operator will also check whether your SIM card supports modern mobile services and will inform you on this subject if necessary.

2. Don’t hesitate to ask for help

Are you unsure whether your device uses the 2G network? Network operators will inform the public more in detail when the actual shutdown draws closer. And you can always ask tech-savvy family members, friends or acquaintances for help. Do you personally know someone who is less familiar with technology? Then give that person a hand to check their phone or devices.

3. Consider purchasing a new device well in advance

Need to replace your device? A new device does not have to be expensive. Do ask whether the device you’re considering supports 4G and/or 5G calls, and whether emergency calls remain possible after the 2G shutdown.

4. Check if you have other devices that may be using 2G

Mobile phones are not the only potential 2G-dependent devices. In some cases, apparatuses such as personal alarm systems, smart meters, alarm systems, passenger lifts, machine-to-machine (M2M) applications and other IoT applications may use 2G as well.
Please contact your supplier or installer to see if these devices need to be adjusted or replaced.

5. Don’t forget the eCall systems in vehicles

Certain vehicles have an integrated emergency call system that uses the 2G network. Check with your manufacturer or dealership whether your vehicle is impacted by the 2G shutdown.

6. Stay informed

Follow your mobile (network) operator to keep abreast of the 2G shutdown schedule and consequences. They will inform end customers about the exact shutdown date of their 2G network and how users should prepare for this. That is why the BIPT recommends end users to pay attention to their operator’s news and general communications – do not ignore these!

Is your operator a Mobile Virtual Network Operator (MVNO) that does not operate its own network? Then keep an eye on the information pages of the mobile network operator (Orange, Proximus, or Telenet/BASE) your MVNO is linked to. On this web page, you can see which network your mobile operator uses.
