Telecommunications operators phase out 2G and 3G networks

Telecommunications operators are proceeding with the planned shutdown of legacy 2G and 3G networks. While these technologies were foundational for voice, SMS, and early mobile internet, they are now considered obsolete as their functions have been integrated into 4G and 5G networks.

The phase-out is driven by several factors, including the high cost of maintaining aging infrastructure and the significant energy consumption of older antennas. A 2023 study indicated that 2G and 3G stations accounted for between 21% and 33% of the electricity consumption in network stations. Decommissioning these networks will also free up radio frequencies for more advanced services and enhance communication security.

According to data from the regulatory authority Arcep, the impact on individual consumers is expected to be minimal. As of late December, approximately 2.6% of terminals still relied on 2G or 3G. While most modern devices are compatible with newer standards, some older hardware and specific machine-to-machine (M2M) professional equipment may be affected by the transition.
