CHIYODA-KU, TOKYO, JAPAN, March 24, 2026 /EINPresswire.com/ — KDDI will expand the lineup of the online version of the data-only eSIM offered to international visitors to Japan, from March 25, 2026, based on customer usage trends.
Two new plans designed for longer stays will be introduced: “Unlimited Data – 5 Days”* and “Unlimited Data – 7 Days”*.
In addition, the service will be provided in the format of a promotion code, with the starting date set by choice of the customers, enabling data usage to start at the timing needed during their stay in Japan.
