Voice Over LTE (VoLTE) And Voice Over Wi-Fi Market

Voice Over LTE (VoLTE) And Voice Over Wi-Fi Market Forecast and Outlook 2026 to 2036

The global Voice Over LTE (VoLTE) and Voice Over Wi-Fi market is on track to achieve a valuation of USD 60,560.2 Million by 2036, accelerating from USD 7,283.7 Million in 2026 at a CAGR of 23.6%. As per Future Market Insights, expansion is structurally underpinned by the global sunsetting of 2G and 3G networks that forces all voice traffic onto IP-based architectures combined with the parallel deployment of 5G standalone cores that enable VoNR. Nokia confirmed in January 2026 the formation of its new Mobile Infrastructure segment merging Core and Radio portfolios to lead the transition toward AI-native networks.

This compels operators to invest in cloud-native IMS platforms that can handle the full migration of circuit-switched subscribers. Simultaneously the regulatory environment is shifting toward stricter emergency call accuracy mandates that increase the dependency on VoWiFi for indoor location precision.

Matthias Sauder, Director Networks at O2 Telefonica, stated: 'This contract extension reflects our shared commitment to advancing 5G technology and creating a more connected and sustainable Germany.' FMI opines that this reflects a broader structural shift where operators are consolidating voice infrastructure modernization with long-term vendor partnerships to reduce the cost and complexity of migrating to all-IP voice delivery.

The operational reality for VoLTE and VoWiFi infrastructure suppliers is defined by the convergence of terrestrial and satellite voice delivery into a single IP-based framework. Bell Canada and AST SpaceMobile completed the first space-based direct-to-cell VoLTE call in Canada in November 2025, proving that high-definition voice can reach unmodified smartphones in remote areas without ground-based tower infrastructure.

AT&T and Nokia extended their strategic partnership in February 2025 to transition AT&T's IMS Voice Core to a cloud-based system, enabling more efficient integration of VoNR while meeting regulatory requirements for sub-50-meter indoor emergency call precision via VoWiFi.

Proximus in Belgium selected Nokia in late January 2026 to modernize its entire voice core for full-scale VoNR on 5G standalone networks. As per FMI, these moves confirm that the VoLTE and VoWiFi sector is entering a phase of infrastructure convergence where cloud-native IMS platforms, satellite-direct voice capability, and indoor emergency call compliance form the three pillars of next-generation voice delivery.
