Internet Initiative Japan Inc.
TOKYO - September 7, 2023 - Internet Initiative Japan Inc. (TSE Prime: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the availability from September 22, 2023 of an eSIM with voice call functionality ("Voice eSIM") for users of the IIJmio mobile service Giga Plan Type D (NTT Docomo network), an MVNO service aimed at individual customers.
IIJmio began Voice eSIM provision last October for its Type A (au network) service.(*1) Besides enabling service activation as early as the same day of purchase, the eSIM can be used as a backup in case of network trouble. These advantages have made it a popular choice and prompted numerous requests for Voice eSIM provision for Type D as well, a need being addressed with the new service offering. The monthly charges for Type D Voice eSIM service are the same as those for a physical SIM with voice call functionality and for Type A Voice eSIM service.
Timed with the start of the new service, IIJ will also support switching from a physical SIM card with voice call functionality to a Voice eSIM, as well as switching between Type A and Type D services. The ability to switch freely between a physical SIM and Voice eSIM, and between Type A and D services, will give customers the advantage of more flexible Giga Plan use based on the mobile device model, service area, carrier or other conditions.

This code is read by the eSIM-conformant device in which the EID was entered. Once the SIM profile has been downloaded, the service can be used.
