All new Samsung phones worldwide will come preconfigured to process high audio quality 4G and 5G voice calls over VoLTE.
New Samsung smartphones will automatically connect to voice services using VoLTE, based on network-specific settings provided via the GSMA’s Network Settings Exchange (NSX) platform. VoLTE will the default settiing on millions of Samsung devices running Android 15 or later.
Calls made over 2G or 3G are handled separately from data, leading to slower call setup and lower audio quality. VoLTE(Voice Over Long Term Evolution) uses a packet-switched IP network, allowing for simultaneous voice and data use, quicker call connections, and improved voice quality with HD audio.
The GSMA’s NSX is a global hub that helps mobile operators share up-to-date network configurations with device manufacturers. It ensures that devices are pre-configured to work smoothly across networks worldwide. Complementing this, the GSMA’s Interoperability Testing service verifies that devices and networks are compatible before launch.
Justin Jun, Head of Quality, Samsung Electronics UK, said:
“Our work with the GSMA means users can count on stable, high-quality voice calls on Samsung devices—no matter where they are.”
Sianne Ryder, General Manager of Services, GSMA, added:
“This is a major step forward in keeping voice services functional and high-quality as older networks are phased out. We hope more manufacturers follow suit.”
