IIJ to Begin Offering "IIJ Mobile Access Service Type I" as a Full MVNO

Providing Japan’s First Full MVNO Service Using Internal 3G/LTE Network

March 15, 2018

TOKYO-March 15, 2018-Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, announced that it will offer IIJ Mobile Access Service Type I (hereafter, Type I) starting today as a full MVNO. This service will both provide a variety of plans that fit different types of usage for corporate customers and achieve more efficient communications costs for specific IoT applications.

Full MVNOs (Mobile Virtual Network Operators) are independent mobile network operators that use wireless access facilities such as bases of mobile network operator (MNOs) by owning Mobile Network Code (MNC) and International Mobile Subscriber Identity (IMSI)(*).
IIJ is Japan's first full MVNO connecting NTT DOCOMO’s 3G/LTE network by maintaining and operating its own subscriber management systems (HLR/HSS) which are part of MVNO core network infrastructure. By having IIJ's own HLR/HSS systems, IIJ is able to manage its own SIM cards and flexibly design various services.
Starting with Type I service, IIJ will be expanding service line-ups, including International roaming options and SIMs that are specialized for being built into devices (so-called "chip SIMs") by leveraging the special characteristics that come with being a full MVNO.

  • (*)Mobile Network Code internationally defines mobile network operator and International Mobile Subscriber Identity defines communications users. By acquiring individual identification number, IIJ can mutually connect mobile network operators within and outside Japan.

Service Highlights

"SIM Life Cycle Management" to streamline SIM's management

"SIM Life Cycle Management" allows a more efficient way of handling SIM maintenance fees by activating and suspending SIM cards. Users can freely switch the status of SIMs from/to activated and suspended. SIM's monthly communications fee is free before activation and when in a suspended its fee is reduced. This is extremely effective for example when customers are dealing with IoT products; when SIMs are in inventory, their status can be suspended and avoid being used in unauthorized and unnecessary ways and also limit the transmission cost component of IoT product life cycle costs.

A variety of plan types to meet customer's usage needs

Type I offers a range of different plan types, including the packet share plan that allow customers to select data transmission volume and subscription models (change to usage based plans, switch over to low speed transmissions, or stop data transmissions) at any time through a web service online, upload priority plans that do not limit upload volumes for devices such as security cameras (transmissions from customer devices to the Internet), and even plans that allow each to have an IP address type (network type) designated by the customer.

SIM management functions via service online and API

Users are able to use SIM Life Cycle Management, acquire SIM information, and order additional SIMs through web service online and by cooperating API. This let monthly communications fee to be reduced by controlling the status of SIM by activating SIM upon when the product is sold. Moreover these functions are very efficient in managing inventory and operation of SIM.

-- Usage Scenarios A for SIM Life Cycle Management --
In cases in which users are manufacturing and distributing IoT products that include SIMs, users can set the SIMs to a suspended status during the period from which the IoT product is shipped until it is sold. End users can activate the SIM when they launch these devices and start transmitting data.
Usage Scenarios A for SIM Life Cycle Management
-- Usage Scenarios B for SIM Life Cycle Management --
In cases in which users apply IoT to the agriculture industry (e.g., when automatically managing water levels in rice paddies), users can limit their transmission maintenance administration fees by setting the transmission state to "suspended" during seasons in which water management is not necessary.
Usage Scenarios B for SIM Life Cycle Management

Service Details

  • 1)Plans
    • Users may choose either a fixed plan or a packet sharing plan.
      • Fixed plan
        This plan provides a fixed data transmission capacity per line. If this fixed transmission capacity is exceeded, the line switches to 256 kbps. Unused transmission capacity can be carried over into the following month.
      • Packet sharing plan
        This plan allows users to share a set data transmission capacity among multiple lines. If the contracted transmission capacity is exceeded, users may choose from the following three options for handling the line:
        Packet Pack A:
        When the contracted capacity is exceeded, data transmissions cease.
        Packet Pack B:
        When the contracted capacity is exceeded, transmissions speeds slow to 256 kbps.
        (*)Packet Pack B is available starting at 50 GB.
        Packet Pack C:
        When the contracted capacity is exceeded, extra fees are charged for the excess transmissions.
        (*)The excess data transmission capacity costs JPY700 per 1 GB.
  • 2)Network Types
  • Users may choose how IP addresses are allocated for each line.
  • < Internet Connections >
    • NAT(*)
      Allocation using dynamic private IPv4 and dynamic global IPv6
    • Global IPv4
      Allocation using dynamic global IPv4 and dynamic global IPv6
    • Fixed IPv4
      Allocation using fixed global IPv4
  • < Closed Network Connections >
  • Closed networks use fixed and dynamic private IPv4 allocation.
    • (*)Network Address Translation (NAT): This technology allows users to access both private IP addresses allocated by corporate intranets and global IP addresses used by the Internet.
  • 3)"Upload Priority Option"
  • This option does not limit upload (from devices to the Internet) transmissions. When the contracted transmission capacity is exceeded, only download transmission rates are limited to 256 kbps, while upload transmissions are not limited.
    • (*)The available data capacity is estimated at 100 GB per month.
