The GSMA has announced a new collaboration with Samsung Electronics, the global mobile industry association, to improve voice call quality and connectivity on 4G and 5G networks. The initiative will see Voice over LTE (VoLTE) enabled by default on all Samsung devices running Android 15 or later, including the recently launched Galaxy S25 series.

VoLTE Enabled by Default on Samsung Devices
This initiative supports a seamless global VoLTE rollout, ensuring that all core telephony services such as emergency calling and roaming remain functional as global mobile operators phase out 2G and 3G networks for higher quality 4G and 5G services, GSMA said in a joint statement on Wednesday, April 30.
By enabling VoLTE by default, Samsung is helping ensure that core telephony services, including emergency calls and roaming, remain functional worldwide. This initiative supports the industry’s transition to higher-quality networks, providing users with consistent and reliable voice services across a variety of operators and regions. Samsung’s efforts align with the GSMA’s Network Settings Exchange (NSX) and Interoperability Testing services, which work together to ensure smooth operator-device compatibility.
GSMA NSX Platform Ensures VoLTE Compatibility
The GSMA NSX platform allows mobile network operators (MNOs) and mobile virtual network operators (MVNOs) to upload and manage their network settings, which are then shared with device manufacturers. This centralised platform enables device manufacturers like Samsung to pre-configure devices with operator-specific settings, ensuring VoLTE compatibility across diverse networks. In instances where specific operator settings are unavailable, devices default to the GSMA Profile #4, according to the official release.
