In Europe, many mobile network operators (MNOs) have completed or plan to switch off their legacy 2G or 3G networks.
These switch-offs are generally not regulated, but in nearly all cases commercially‑driven, allowing operators to:
- increase the spectrum available for new mobile technologies by re-farming 2G or 3G spectrum for the use of 4G and 5G; and
- generate network cost savings through lower network maintenance costs.
One of the reasons for the continued use of such legacy mobile networks is that they are still used, especially 2G networks, for machine-to-machine (M2M) services, such as smart meters and e-call systems.
Cullen International’s latest European benchmark shows that MNOs in 22 out of the 31 countries researched have completed or have plans to switch off their legacy 2G or 3G networks.
One MNO in Switzerland, Swisscom, switched off its 2G network in April 2021. MNOs' plans to switch off 2G networks exist in eight other European countries.

In only three countries, Czech Republic, Hungary and Italy, did the regulators become involved in whether 2G or 3G networks should be switched off.
Cullen International also has a similar benchmark on the 2G/3G switch-off in the MENA region.
