IIJ to Launch "IIJmio eSIM Service Data Plan Zero," an eSIM Service for Consumer Use

An official eSIM service with data transmission service plans from 1 GB, for as much data usage as necessary, when necessary

March 17, 2020

TOKYO-March 17, 2020-Internet Initiative Japan Inc. (TSE1: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the March 19 launch of IIJmio eSIM Service Data Plan Zero, an eSIM-compatible data transmission service for consumer mobile users.

eSIMs are embedded SIMs for smartphones and other devices that allow users to remotely download the profiles needed to use telecom services, without having to remove the physical SIM card. Users can readily start transmitting data and switch telecom carriers just by downloading profiles to their eSIM-ready smartphones or tablets, rather than inserting SIM cards as they had done before. With the ongoing increase in compatible devices, eSIMs promise rapid market growth.

Since leading off with this service in July 2019, IIJ has offered a beta test of Japan's first eSIM service (6 GB for JPY 1,520 per month), receiving subscriptions for more than 10,000 lines. In light of the requests received from beta version users during this period, IIJ has improved the service's usability and performance. Now it will launch the IIJmio eSIM Service Data Plan Zero as the official version of the service.

Unlike conventional service plans that use set monthly data transmission volumes, this service has no attached data transmission volumes, so users can add as much data as they need, when they need it. Users can keep their existing carrier's service and add this service as a second line. They can then switch to their IIJmio eSIM and add data if they run out of data during the month or just before their fisrt line's fees increase to the higher level. This flexibility allows users to keep their monthly fees down, making data transmission available at a low cost.
