■How to use “Osaka eSIM”

■About communication services for foreign travelers offered by the Osaka Convention & Tourism Bureau
In January 2014, the Osaka Convention & Tourism Bureau began offering free public Wi-Fi (Osaka Free Wi-Fi, or OFW) for people visiting Osaka, especially tourists from overseas.
In addition, the Bureau worked with Wire and Wireless Co., Ltd. to offer “Osaka Free Wi-Fi OpenRoaming” from October 2024, which is compatible with “OpenRoaming” (note 3), an international standard of authentication which is being increasingly adopted in Europe, the United States, and Japan, with the goal of expanding OFW and making it more comfortable to use.
In addition to OFW, which can only be used in specific places, the Bureau also offers “Osaka eSIM,” which covers a wide area and can be used easily during transit. A large number of tourists are expected to visit Osaka for Expo 2025, and the Bureau is striving to provide a comfortable and seamless communications environment and increase the satisfaction of visitors.

■About povo SDK
Povo SDK is an open communications service that allows companies to incorporate povo’s communication service and offer their own plans. Music and video subscription services, e-tickets, and smart phone payments have become increasingly more widespread, amplifying the need for an internet connection in people’s daily lives.
This allows companies to offer unlimited data for specific services or original toppings that other companies don’t carry. The duration and data amount can also be customized, allowing the company to provide appropriate toppings to suit the customer’s needs.
