PDF format

Japan Communications Inc. (TSE Prime: 9424; hereinafter referred to as "JCI”) is pleased to announce that, as of December 3, 2024, it has entered into a contract with ng-voice GmbH (Headquarters: Hamburg, Germany; CEO: David Bachmann, hereinafter referred to as "ng-voice"), the developer of the Hyperscale IMS (IP Multimedia Subsystem) solution for its voice services.

As previously announced on February 14, 2024, JCI is working towards the launch of its "Neo-Carrier" service by May 24, 2026. This service will be realized by connecting voice, SMS, and data networks to MNOs, breaking free from the constraints of MNOs. JCI has already begun constructing its voice and SMS networks, and the implementation of ng-voice's Hyperscale IMS solution marks a significant step toward the realization of its Neo-Carrier vision.

In recent years, the full IP transition of mobile networks and advancements in cloud technologies have made it possible for JCI to build its Neo-Carrier infrastructure with unparalleled cost competitiveness. JCI has been in discussions with IMS development companies in the United States, Europe, and Asia. ng-voice, having developed IMS from the ground up for the cloud, excels in scalability, flexibility, and automation of control, outpacing competitors in these areas. This IMS solution with its high level of automation, resilience and flexibility aligns perfectly with JCI's corporate strategy, enabling the company to maintain its cost leadership in providing voice services.

Moreover, as an IMS-specialized manufacturer, ng-voice is leading the way in leveraging IMS functionalities to provide innovative new services. JCI, in collaboration with ng-voice, will not only focus on providing voice services but will also continue to develop and offer new, cutting-edge services.

Dr. David Bachmann, CEO of ng-voice, comments “We are thrilled to be part of JCI’s “Neo Carrier” project, bringing disruptive MVNO services to Japan. We are excited about our partnership with JCI, a pioneer known for bringing innovation to the Japanese telecommunications markets for decades.”

Naohisa Fukuda, COO of JCI, comments “In a society where digitalization is advancing, the need to transport digital bits safely from Point A to Point B—and to do so as cost-effectively as possible—has become increasingly important. Communication serves as a critical infrastructure in the digital age, underpinning the development of various applications deployed on it by ensuring safety and affordability. ng-voice is a trusted partner in achieving these goals, and we look forward to unlocking new possibilities through our collaboration with them.”
