The GSM Association (GSMA) has partnered with Samsung Electronics to accelerate the global deployment of voice over long-term evolution (VoLTE), enhancing call quality and connectivity over 4G and 5G networks.
Under this collaboration, Samsung will enable VoLTE by default on all devices running Android 15 or later, including the new Galaxy S25 series.
As mobile operators worldwide continue phasing out legacy 2G and 3G networks, the move ensures critical services such as emergency calls and roaming remain uninterrupted. Samsung’s integration supports GSMA-led initiatives like the Network Settings Exchange (NSX) and Interoperability Testing services, providing more consistent and reliable voice services across global markets.

The GSMA NSX platform simplifies how operators deliver updated network settings to device manufacturers. It allows mobile network operators (MNOs) and mobile virtual network operators (MVNOs) to upload, manage, and distribute information management system (IMS) configurations, which device makers like Samsung can then implement. Where specific operator settings aren’t available, Samsung devices will default to GSMA Profile #4 for VoLTE compatibility.
Justin Jun, Head of Quality, Head of Group UK at Samsung Electronics, said, “Our collaboration with GSMA has strengthened Samsung’s VoLTE compatibility, enabling more stable and seamless voice services across networks and regions. We’re excited to keep advancing connectivity so users can count on an exceptional mobile experience, wherever life takes them.”

To ensure seamless performance, Samsung is also adopting GSMA-standard testing protocols to validate VoLTE functionality before commercial rollout. Through the GSMA’s Interoperability Testing service, both parties are helping operators evaluate device readiness and ensure compliance before launch.
This collaboration underscores the importance of industry-wide cooperation in advancing mobile voice services and supporting a future-ready, high-quality connectivity ecosystem.
Sianne Ryder, General Manager, Services, at the GSMA, added, “As more and more countries phase out 2G and 3G networks to repurpose spectrum for 5G, it is essential to ensure that voice services continue to function seamlessly. We look forward to more manufacturers following Samsung’s lead in enabling VoLTE connectivity across networks. By doing this, we can significantly improve global connectivity and user experience (UX), ensuring users can benefit from seamless and high-quality voice services, regardless of their network environment.”
