Definition
The 2G and 3G Switch Off Market refers to the global transition away from legacy second-generation (2G) and third-generation (3G) mobile networks toward more advanced 4G LTE, 5G New Radio (NR), and soon 6G-ready infrastructures. This market encompasses the policies, investments, technological processes, vendor activities, and strategic network shutdowns undertaken by mobile network operators (MNOs) globally to reallocate valuable spectrum resources toward faster, more efficient, and more monetizable technologies.

This transition is not merely a network upgrade—it is a full-scale global ecosystem transformation. It includes:
- Decommissioning legacy BTS, NodeB, MSC and RNC systems
- Refarming low-band spectrum (700 MHz, 800 MHz, 900 MHz) for 4G and 5G
- Shifting IoT and M2M connections to LTE-M and NB-IoT
- Massive reconfiguration of backhaul and core networks
- Customer migration strategies for voice, data, and enterprise IoT services
- Device ecosystem modernization (VoLTE-capable phones, CAT-M devices, etc.)
The 2G/3G shutdown wave is driven by a mix of economic, technological, and regulatory imperatives. These include rising OPEX associated with aging hardware, energy inefficiencies, spectrum scarcity, and the global push for digital transformation.
Globally, operators such as AT&T, Verizon, China Mobile, Deutsche Telekom, Orange, Telefónica, NTT, and América Móvil have already initiated large-scale sunset programs, often spanning multiple countries and requiring coordination between regulators, enterprises, and consumers.
Market Size
Global 2G and 3G Switch Off market was valued at USD 1,636,580 million in 2024. The market is projected to grow from USD 1,712,000 million in 2025 to USD 2,249,510 million by 2032, with a CAGR of 4.8% during the forecast period.
Several factors are driving this growth:
- Reallocation of Spectrum for 4G/5G
Spectrum refarming represents one of the largest revenue generators in this space. Operators gain substantial financial benefits from reallocating previously underutilized 2G/3G frequencies to high-speed broadband. - Massive Reduction in Operational Expenditure
Switching off 2G and 3G can cut energy consumption by 70–90% across sites due to the removal of inefficient legacy hardware. - Explosion in IoT and M2M Modernization
IoT devices relying on 2G and 3G are being upgraded worldwide to LTE-M/NB-IoT platforms. - Government-Led Digitalization Programs
Countries across the EU, Asia-Pacific, the Middle East, and the Americas are issuing directives for 2G/3G sunset timelines to accelerate national connectivity innovation. - Enterprise Migration and Network Modernization Deals
Telecom vendors, system integrators, and managed service providers are seeing significant revenue from modernization projects across industries like automotive, utilities, smart cities, and healthcare.
Regional Analysis
North America
The U.S. has the world’s most advanced 2G/3G shutdown ecosystem. AT&T switched off 3G in February 2022, and Verizon completed its 3G shutdown in December 2022. Canada discontinued most 2G capacities, focusing entirely on LTE and 5G. The region leads in VoLTE adoption, enterprise IoT migration, and advanced spectrum refarming strategies.
