Strong 4G and 5G coverage, high smartphone penetration, and growing enterprise demand for secure connectivity have supported faster legacy network retirement. Telecom providers are also modernizing infrastructure to reduce operating complexity and support data-heavy digital services.

For instance, in December 2025, Intel decided to retain and strengthen its Networking and Edge Group rather than spin it off, positioning the unit to support traffic growth as 2G and 3G are retired and 4G/5G usage soars in North America. Its edge and cloud silicon help operators handle post-sunset data and signalling loads.

Network Type Analysis

In 2025, the Mobile Network segment held a dominant market position, capturing a 91.3% share of the Global 2G and 3G Switch Off Market. This dominance is due to the direct role of mobile operators in retiring older network layers and shifting users toward advanced connectivity. Mobile networks remain central to spectrum planning, service migration, and coverage management, which makes them the main platform for 2G and 3 G switch-off programs.

Operators are also focused on reducing the cost and complexity of running multiple legacy systems. By moving traffic to newer networks, they can improve data performance, strengthen service reliability, and manage infrastructure more efficiently. This supports smoother migration for both consumer users and enterprise customers.

For instance, in July 2025, Ericsson shared guidance on how operators can turn 2G and 3G mobile network sunsets into a smooth path to 5G, focusing on smarter spectrum use and simplified radio layers. This kind of support helps carriers retire old mobile networks with less risk and keeps demand high for mobile network modernisation in the switch-off market.

Technology Analysis

In 2025, the 3G segment held a dominant market position, capturing a 60.2% share of the Global 2G and 3G Switch Off Market. This dominance is due to the faster retirement of 3G networks in many countries, as their role in mobile data services has declined. Operators are prioritizing 3G shutdown because most users have already moved toward newer devices and faster network services that offer better performance.

The 3G layer also requires continued maintenance, power, and spectrum resources, even though its commercial value is reducing. By shutting it down, telecom providers can reuse resources for stronger 4G and 5G coverage. This helps improve network quality while supporting modern digital applications.

For instance, in July 2025, GSA reported hundreds of completed or planned 2G and 3 G switch-offs across dozens of countries, reflecting active work by infrastructure vendors like Nokia, Huawei, and ZTE. As operators move ahead with 3G retirements, they lean on these suppliers for replacement equipment and tools, driving growth in the 3G focused technology segment.

Application Analysis

In 2025, the Data segment held a dominant market position, capturing a 45.8% share of the Global 2G and 3G Switch Off Market.

Data migration is becoming important as users expect stable speed and better service quality on mobile networks. Enterprises also need stronger connectivity for monitoring, automation, and digital operations. This is pushing operators to move traffic onto newer networks that can handle modern data demand more effectively.

For instance, in April 2024, at MWC, Huawei highlighted that traditional indoor systems built for 2G and 3G struggle with modern data demands and promoted digital fiber-based solutions. By positioning new indoor platforms that favour 4G and 5G data, Huawei is directly supporting projects that phase out legacy layers in high traffic locations.

End-User Industry Analysis

In 2025, the Telecommunications segment held a dominant market position, capturing a 70.6% share of the Global 2G and 3G Switch Off Market. This dominance is due to telecom operators being the main decision makers in legacy network shutdown programs. They control the timing, spectrum use, customer migration, roaming updates, and infrastructure changes needed to retire 2G and 3G services without disrupting critical connectivity.

Telecom companies also benefit directly from simplifying their network structure. Fewer legacy systems can reduce maintenance pressure, improve energy use, and support better service management. This allows operators to focus investment on advanced networks while helping customers move toward safer and more capable connectivity options.

For instance, in December 2025, the Global Mobile Suppliers Association reported hundreds of completed or planned 2G and 3 G switch-offs across many countries, most led by network operators seeking to modernise infrastructure. This shows how telecom providers remain at the centre of the market, steering investment and timelines for legacy shutdowns.

Emerging Trends

Telecom operators are shifting faster toward 4G, 5G, and LTE-based IoT networks as older mobile systems become less efficient. A key trend is spectrum refarming, where unused 2G and 3G bands are reassigned to newer services that can support better coverage, faster data, and stronger network performance.

Another trend is the planned migration of legacy connected devices used in utilities, transport, security, and industrial operations. Businesses are reviewing old SIMs, modules, and machine connections before shutdown dates. This is creating demand for device audits, replacement plans, and managed connectivity support across enterprise networks.

Growth Factors

The growth of 2G and 3 G switch-off is supported by rising mobile data use, higher demand for reliable connectivity, and the need to reduce legacy network costs. Operators are retiring older systems to simplify operations and improve service quality across consumer, business, and IoT applications.

Drivers

Spectrum Refarming for 4G and 5G

Spectrum refarming is a major driver as operators need to reuse limited frequency bands for faster and more efficient mobile networks. Older 2G and 3G layers consume valuable spectrum that can support stronger 4G and 5G coverage, better data capacity, and improved service quality for modern users.

This shift also helps operators reduce the burden of maintaining several network generations at the same time. By moving traffic to newer technologies, telecom providers can simplify infrastructure, improve energy use, and offer more reliable mobile services for consumers, enterprises, and connected devices.

For instance, in December 2025, Samsung New Zealand supported the national 3G shutdown by advising users to move to 4G-capable devices, explaining that freeing 3G spectrum helps deliver more reliable 4G and 5G services. The company worked with local operators and industry groups to check handset readiness, encouraging upgrades that enable future use of refarmed spectrum.

Restraint

Legacy Device Dependence

Legacy device dependence remains a key restraint because many machines, alarms, meters, trackers, and payment terminals still rely on older mobile networks. These devices often have long service lives and may be installed across wide locations, making replacement difficult, costly, and time-consuming for businesses.

Enterprises also need to test device compatibility, update contracts, and manage service continuity before migration. In sectors such as utilities, transport, healthcare, and security, even a small service gap can create operational risk. This slows the pace of shutdown and increases planning pressure.

For instance, in December 2025, Huawei’s 2025 support article explained that when VoLTE is disabled, phones drop from 4G to 2G or 3G during calls and return to 4G afterward. This behaviour reveals the ongoing reliance on legacy networks for basic voice on many devices, making it harder for operators to fully switch off 2G and 3G without widespread VoLTE activation.

Opportunities

Managed Migration Services

Managed migration services offer a strong opportunity as businesses need expert support to move away from 2G and 3G connectivity. Many firms do not have full visibility into their connected devices, contracts, SIM profiles, and field assets, creating demand for structured audits and migration planning.

Service providers can support device replacement, network testing, deployment, monitoring, and long-term connectivity management. This creates value for telecom operators, IoT vendors, system integrators, and platform providers. The opportunity is especially strong in industries with large device fleets and critical field operations.

For instance, in December 2025, Intel’s support for virtualized and cloud-native network functions allows carriers to replace legacy 2G/3G core elements with software on standard hardware. This creates space for consulting and integration projects where Intel and partners help operators decommission old systems and shift services into flexible 4G and 5G core environments.

Challenges

Coordinating Regulation and Timelines

Coordinating regulation and timelines is a major challenge because shutdown plans differ across countries, operators, and service types. Businesses with regional or global operations must track different deadlines, roaming changes, device rules, and customer communication needs to avoid unexpected service gaps.

Clear planning is required between telecom operators, regulators, enterprises, and equipment vendors. Delays, unclear notices, or uneven readiness can create migration pressure near shutdown dates. This is especially difficult for critical services where devices must remain connected during the full transition period.

For instance, in July 2025, Ericsson discussed 2G and 3G sunsets as a business opportunity but stressed the challenge of managing transition for voice and M2M services under different national rules and schedules. The company highlighted the need for coordinated hardware and software strategies to align with regulatory expectations while operators migrate.
