Why and when will 2G and 3G networks be discontinued? 

These technologies have been in use since the 1990s, and are gradually becoming obsolete. They are being replaced by more modern, secure and energy-efficient networks. 

In many European countries, the 2G and 3G networks are not being switched off simultaneously across all operators. In practice, even when some operators switch off their networks, at least one operator will continue to provide 2G or 3G connectivity during a transitional period, to ensure continuity of service for critical applications (security, alarms, telemetry, industrial equipment, etc.). 

Here is the provisional schedule for switching them off in Europe:

Operator	2G switch-off	3G switch-off
France	Switch-off expected at the end of 2026	Will start in 2028 until end of 2029
Belgium	Planned switch-off: end of 2027	The process has already begun and will continue until 2030
Spain	Switch-off expected by the end of 2030	Switch-off expected by the end of 2027
Luxembourg	Switch-off expected by the end of 2030	Switch-off expected at the end of 2025
Germany	No official announcement.	No official announcement
Switzerland	The network was switched off in 2023	Switch-off expected at the end of 2025
United Kingdom	Switch-off expected by the end of 2033	Switch-off expected by the end of 2025
Italy	No official announcement	Switch-off expected by the end of 2025

Does it affect me?  

It affects you if:

• You have a TTGSM transmitter or a Tydom 315: these 2 products work on 2G*.

• Or a Tydom 2.0 that works on 2G and 3G

Visuals of the products affected by the evolution of 2G and 3G networks

If you have any doubts, do not hesitate to ask your installer. 

Do not worry, your equipment will keep working if you have a smart home hub (Tydom or Tywell). They will still detect intrusions and send you alerts via the Tydom app even after 2G and 3G networks are switched off.  

All you have to do is allow notifications in the application:

• Settings > House > Notifications, then activate the desired notifications (intrusion, technical alerts for smoke and water leak detectors, etc.). 

However, if you want to continue receiving alerts by SMS or phone call, you will need to upgrade your installation. 

The new solution: the Tyxal+ Hub (spring 2026) 

From spring 2026, Delta Dore will be offering a new connected control unit: the Tyxal+ Hub. Here is a sneak preview of its features. It will allow you to:

• Continue to receive SMS alerts and calls on 4G 

• Benefit from a more modern connection: Ethernet, Wi-Fi and/or 4G

• Control your alarm via the Tydom application

• Keep your existing Tyxal+ equipment: door/window magnetic contact detector, smoke detector, etc. 

It is the ideal solution for upgrading your system without replacing everything. 

Why use a Delta Dore-approved installer? 

Your installer is your most valuable ally in maintaining your security and peace of mind:

About the product warranty :

The evolution of telecom networks (like the switch off of the 2G and 3G networks) depends exclusively on telephone operators. As such, these changes are excluded from the product warranty, in accordance with the Delta Dore warranty conditions. 

This does not prevent your installation from continuing to function. Delta Dore and its network of installers are also available to assist you in upgrading your system if you wish to retain specific features, such as SMS or call alerts. 

^{* Please note that products in the former Tydom 320/330, CTX60, Deltal and Deltis alarm ranges also work in 2G.}
