# Global 2G and 3G network decommissioning > Live situation record from CLSTR: https://clstr.news/situations/global-2g-and-3g-network-decommissioning > Updated: 2026-09-07T01:55:47.000Z. Sources: 17. Developments: 4. Europe is leading the global transition to decommission legacy 2G and 3G mobile networks to repurpose spectrum for 4G and 5G. According to the Global Mobile Suppliers Association (GSA), 43% of all network switch-offs are concentrated in Europe, followed by Asia (26%) and Latin America (9%). While 3G decommissioning is progressing—with 102 operators having completed the process—2G remains more resilient due to its role in machine-to-machine (M2M) communications and the Internet of Things (IoT). The phase-out presents significant risks to critical infrastructure. Automated emergency systems like eCall, medical equipment, elderly assistance bracelets, and truck trackers may lose functionality. In Spain, concerns persist regarding elevators that rely on 2G for emergency calls, though 4G coverage remains high at 99.99%. In La Réunion, SFR has confirmed a 2G shutdown date of November 30, 2026. In France, the transition has sparked intense debate. The association Hop estimates up to 12 million devices could be affected. Industry professionals have criticized operator timelines as “unrealistic,” arguing that upgrading equipment involves complex industrial manufacturing rather than simple SIM card changes. The Elevator Federation has specifically highlighted that over one-third of the French elevator fleet relies on 2G technology. Beyond infrastructure risks, the decommissioning process intersects with growing cybersecurity concerns. 2G networks are noted for being highly vulnerable because they lack mutual authentication, allowing attackers to use devices such as “SMS Blasters” or “False Base Stations” to mimic legitimate towers and intercept communications. In response to these vulnerabilities, Google is introducing features in Android 17 that will allow operators to disable 2G by default, offering a ‘zero click’ layer of protection for users. ## Claims - Up to 12 million devices are threatened with obsolescence due to the phase-out of 2G and 3G networks. (corroborated by 4 sources) - More than one-third of the French elevator fleet, approximately 230,000 out of 661,000 devices, relied on 2G at the end of last year. (corroborated by 4 sources) - Public authorities cannot intervene in network operators' decisions without violating European Union law. (corroborated by 4 sources) - The government maintains that professionals have been provided with sufficient time to transition. (corroborated by 2 sources) - The 2G network in La Réunion will be shut down on November 30, 2026.

Android 17 aims to mitigate these vulnerabilities by allowing default 2G deactivation. 2 sources. https://clstr.news/cluster/global-2g-and-3g-network-shutdowns-drive-security-and-infrastructure-shifts ### 2026-08-26: 2G network shutdown threatens critical infrastructure and devices The shutdown of 2G and 3G networks threatens millions of devices, including critical medical, emergency, and elevator communication systems, as operators transition to 4G and 5G. 6 sources. https://clstr.news/cluster/2g-network-shutdown-threatens-millions-of-devices-and-essential-services ### 2026-08-24: 2G and 3G network shutdowns threaten IoT and emergency systems The global phase-out of 2G and 3G networks to make room for 5G threatens IoT devices, including emergency systems in elevators and home alarms, particularly in Spain. 3 sources. https://clstr.news/cluster/2g-and-3g-network-shutdowns-threaten-iot-and-emergency-systems ### 2026-08-17: Europe leads global 2G and 3G network decommissioning Europe leads the global decommissioning of 2G and 3G networks, a transition that impacts IoT devices and vehicle emergency eCall systems as operators shift toward 4G and 5G infrastructure. 6 sources. https://clstr.news/cluster/europe-leads-global-2g-and-3g-network-decommissioning --- Cite as: Global 2G and 3G network decommissioning.
