IP Multimedia Subsystem Market Analysis & Forecast: 2026-2033
The IP Multimedia Subsystem Market size is anticipated to grow at a CAGR of 13.2% with USD 4.4 Bn in 2026 and is expected to reach USD 10.5 Bn in 2033. The primary drivers are defined by accelerating 5G standalone deployment, migration from circuit-switched networks to all-IP infrastructure, expanding Voice over LTE and Voice over New Radio adoption, and rising demand for converged communication services. According to the International Telecommunication Union, approximately 9.2 billion mobile-cellular subscriptions were active globally in 2025, while 5G networks covered around 55% of the global population. These developments are strengthening demand for cloud-native IMS platforms, session control, multimedia application servers, VoLTE, VoWi-Fi, VoNR, and carrier-grade communication services.
On the basis of mode of communication, the mobile/wireless segment is projected to account for the largest IP Multimedia Subsystem Market share of 74.2% in 2026. The segment’s growth is owing to the global installed base of mobile subscriptions, broad LTE availability, rapid 5G deployment, increased smartphone use, and continuing adoption of operator-controlled voice services.
IMS is essential to mobile communication because 3GPP identifies VoLTE and VoNR as communication services delivered by IMS over 4G and 5G networks. The same service platform can support communication over wireless local-area networks and other access technologies. This common architecture allows operators to provide consistent identities, call features, emergency access, supplementary services, and charging across LTE, 5G, and Wi-Fi.
India illustrates the scale of wireless-led demand. The Ministry of Communications reported that India had approximately 1.244 billion mobile subscriptions at the end of December 2025. The country also recorded 1.259 billion combined mobile and 5G fixed-wireless-access subscriptions.

On the end user, the consumer segment lead with a major 57.5% share in 2026. The growth is owing to the rising use of IMS-supported VoLTE, VoWiFi, VoNR, video calling, and rich messaging across smartphones and connected devices.
The International Telecommunication Union reported 99 mobile-broadband subscriptions per 100 inhabitants worldwide in 2025, while mobile broadband represented 89% of all mobile subscriptions, indicating a large addressable consumer base for operator-managed multimedia services.
In February 2025, Mavenir and O2 Telefónica Germany signed a five-year extension to migrate fixed and mobile networks from virtualized IMS to cloud-native IMS. The platform supports VoLTE and VoNR, maintains 4G-to-5G voice continuity, and allows for scalable service innovation. These developments strengthen the consumer adoption by improving voice quality, network resilience, service availability, as well as multimedia experiences across operator networks globally.
Germany is emerging as an important market for cloud-native IMS innovation. This is because the operators are replacing virtualized network functions with containerized platforms running across private and public cloud environments. The transition is supported by high LTE and 5G availability, extensive enterprise connectivity, and operator requirements for lower operating costs, automated software updates, elastic scaling, and faster service introduction.
The Bundesnetzagentur reported that 5G services were available across approximately 95% of Germany’s surface area by October 2025, increasing from around 93% a year earlier. Deutsche Telekom provided 5G coverage over approximately 87% of the country’s surface area, while Vodafone and Telefónica covered around 75% and 76%, respectively. This network footprint creates a substantial base for IMS-supported VoLTE, VoNR, VoWi-Fi, emergency calling, enterprise communications, and multimedia applications.
In May 2026, Mavenir announced that Telefónica Germany had migrated the first 100,000 mobile subscribers to 4G and 5G voice services on Mavenir’s cloud-native IMS platform running on Amazon Web Services. The milestone made Telefónica Germany the first European mobile operator identified by the companies as operating production mobile voice subscribers through this type of public-cloud deployment.

The North America region accounts for 41.3% of the market share in 2026. The region’s growth is owing to the extensive LTE and 5G infrastructure, high smartphone penetration, a substantial interconnected VoIP base, mature cloud-computing ecosystems, and ongoing transition toward IP-based emergency services.
The U.S. had approximately 473 million retail voice connections in June 2025. This included 394.5 million mobile subscriptions, 63.4 million interconnected VoIP subscriptions, and 15 million switched access lines. Mobile subscriptions increased at a compound annual rate of approximately 2.5% between June 2022 and June 2025, while switched access lines declined by 17.9% annually. This installed base creates continuing demand for IMS capacity expansion, security, signaling, policy integration, service assurance, number management, emergency communication, and migration services.
In February 2025, ng-voice entered a partnership with U.S.-based Cirrus Core Networks to combine its cloud-native Hyperscale IMS with managed-network and systems-integration services. The partnership targets MVNOs, communication service providers, and industrial customers requiring VoLTE, VoNR, VoWi-Fi, mobile-core, and value-added services.
Asia Pacificis expected to witness strong growth in market over the forecast period. The region’s growth is owing to the large mobile-subscriber populations, rapid 5G infrastructure deployment, increasing smartphone adoption, network modernization, and the retirement of legacy voice technologies.
The GSMA reported that Asia Pacific had approximately 1.5 billion mobile-Internet users in 2025 and projected that 5G would represent around 50% of the region’s mobile connections by 2030. India, China, Japan, Indonesia, Pakistan, and other emerging economies are expected to contribute a substantial proportion of new mobile-Internet subscribers.
In March 2026, Ericsson announced plans to modernize SoftBank’s Japanese core network, including migration of the operator’s IMS platform to Ericsson Cloud IMS.
