Global mobile communications industry group GSMA has partnered with Korean tech giant Samsung Electronics 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.
Under the partnership, all Samsung devices using Android 15 or above 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.
The GSMA NSX is a centralised platform designed to streamline and standardise the distribution of mobile network settings from operators to device manufacturers (OEMs) globally.
It allows MNOs and 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," GSMA says.
"Device manufacturers can also pre-configure devices as per the shared network settings of each operator on the hub."

GSMA’s Interoperability Testing service provides a suite of validation tools that confirm operator-device compatibility for VoLTE prior to commercial deployment.
In addition to turning VoLTE on by default, Samsung has also aligned its testing regimen with GSMA-standard VoLTE testing procedures.
GSMA and Samsung plan to help operators assess VoLTE readiness through standard tests, and GSMA is also providing Interoperability Testing services to help operators with VoLTE pre-launch testing in collaboration with Samsung.
“Our collaboration with GSMA has strengthened Samsung’s VoLTE compatibility, enabling more stable and seamless voice services across networks and regions," said Justin Jun, Head of Quality, Head of Group UK at Samsung Electronics.
"We’re excited to keep advancing connectivity so users can count on an exceptional mobile experience, wherever life takes them.”
Sianne Ryder, General Manager, Services at the GSMA said the collaboration with Samsung is a significant step forward.
"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," Ryder said.
"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, ensuring users can benefit from seamless and high-quality voice services, regardless of their network environment.”
