The Global System for Mobile Communications Association GSMA, representing the interests of mobile operators worldwide, and Samsung Electronics forge a new partnership to improve voice call quality and connectivity over 4G and 5G networks by enabling VoLTE Voice over LTE by default on devices running Android 15 or later. The collab aims to push a seamless global VoLTE rollout across the networks.
The partnership looks forward to ensuring that all critical and core telephony services, like emergency calling and roaming, remain functional as global mobile operators phase out 2G and 3G networks for higher-quality 4G and 5G services. Samsung will be working in close alignment with the GSMA’s Network Settings Exchange NSX and Interoperability Testing services.
Ensuring Consistent & Reliable Services
Through this, Samsung aims to enable consistent and reliable voice services across a wide range of operators and regions by default. All Samsung devices using Android 15 or above, including the recently launched Galaxy S25 series, are being equipped to access high-quality VoLTE where supported, using operator-defined IMS settings via NSX or defaulting to GSMA Profile #4 when necessary.
Moving Towards Pre-Configured Devices
The partnership aims to enable mobile network operators MNOs and mobile virtual network operators MVNOs to upload, manage, and distribute their latest network settings. Through GSMA NSX, operators can share IMS-specific settings with device manufacturers to ensure seamless service functionality and interoperability. Device manufacturers can also pre-configure devices as per the shared network settings of each operator on the hub.
Equipping the Latest Technology
Samsung and the GSMA are partnering to support operators in assessing VoLTE readiness through standardized testing, emphasizing the value of industry-wide collaboration. As part of this effort, the GSMA is offering interoperability testing services to assist operators with VoLTE pre-launch validation in close cooperation with Samsung.
