Japan Communications Inc. (Stock code: 9424, hereinafter referred to as "JCI") is pleased to announce that on June 25, 2025, the Ministry of Internal Affairs and Communications (hereinafter referred to as "MIC") allocated JCI a mobile phone number (11-digit number starting with 090 or other numbers). This is the first time that an MVNO (mobile virtual network operator) will be assigned mobile phone numbers in Japan. It is the result of a policy decision by the MIC's Information and Communications Council in December 2021 and a system reform in February 2023. The interconnection with voice and SMS network requires the allocation of mobile phone numbers. This allocation makes steady progress toward the interconnection with voice and SMS networks.
Going beyond the traditional MVNO business model and being freed from the contractual and technical constraints imposed by MNOs (mobile network operators), JCI is embarking on its journey to become a "Neo-Carrier" that provides interconnected voice, SMS, and data communications.
This marks a shift to a new stage where JCI can compete with MNOs and achieve essential independence as a telecommunications operator.
Following a 2007 ruling by the MIC, JCI achieved interconnection with NTT DOCOMO's data communication network. However, interconnecting with NTT DOCOMO's voice and SMS network had been impossible for a long time because the system did not allow MVNOs to receive allocations of mobile phone numbers. However, in December 2021, the MIC's Information and Communications Council announced its policy on designating telephone numbers to MVNOs. In June 2022, JCI requested NTT DOCOMO to interconnect the host MNO network with our own core network, and JCI achieved an agreement in February 2024. JCI is currently coordinating interconnections with domestic telecommunications carriers and building an emergency call network (110, 119, etc.), as well as building core network functions such as HSS (Home Subscriber Server), IMS (IP Multimedia Subsystem), SMSC (Short Message Service Center), etc. Our internal operational tests are almost complete. Following the allocation of mobile phone numbers, we will proceed with tests assuming linkage with NTT DOCOMO's base stations. We are now in the midst of full-scale preparations for the scheduled launch of the new service on May 24, 2026.
Naohisa Fukuda, president and CEO of JCI, comments “Wholesale contracts are generally subject to the other company's circumstances and have many unclear points. However, now that a sustainable system based on the interconnection has been established under the Telecommunications Business Act, a clear exit for the future is in sight. The path to interconnection is challenging, but we are confident that we will surely reach the next stage — and beyond. This is also a moment when we see signs of hope, like seeing a rainbow over a vast plain. We will use this opportunity as a new starting point and continue to take on bold challenges as a ‘truly independent telecommunications operator = neo-carrier.’”
< The “Neo Carrier” Concept and Its Significance >
Once voice communication networks are interconnected, JCI will be able to use all of the data, voice, and SMS networks on a cost basis going forward. More precisely, the price must not exceed the amount of the appropriate costs under efficient management plus appropriate profit, in accordance with the Telecommunications Business Act. At the same time, JCI will be able to provide services with greater flexibility than we currently offer. We see this as the birth of a “Neo-Carrier,” a new type of carrier.
< Initiatives to Realize a Low-Cost Carrier >
Through collaboration with 21 vendors across six countries, we are developing a core system that effectively integrates network functions, including HSS, IMS, and SMSC. By selecting the optimal technology for each function, we have reduced the overall system investment costs to a fraction of conventional levels. In addition, we have achieved low-cost operations in various areas, including network operations, dealer commissions, sales, and personnel expenses. We are more cost-efficient and competitive than MNOs.
JCI will continue to pursue its mission of "carrying bit in safety and security" and will contribute to society through its services and products, aiming to build a sustainable digital society and enhance its corporate value.
