Corporate Wi-Fi Rental Service "Wi-Ho!Biz" 5G Unlimited Plan Coverage Expands to Industry-Leading 81 Countries/Regions*

Telecom Square, Inc. (Headquarters: Chiyoda-ku, Tokyo; President: Yuji Yoshitake; hereinafter "the Company"), a provider of cross-border mobile communication solutions worldwide, will expand the lineup of countries and regions covered by its 5G Unlimited Plan for its corporate communication service "Wi-Ho!Biz" starting July 2, 2026 (Thu), making it available in a total of 81 countries and regions. The 5G Unlimited Plan will offer the industry's leading number of supported countries and regions for major corporate overseas Wi-Fi rental services in Japan, enabling companies with diverse overseas business trip destinations to cover a wider area with a single service.

In recent years, while overseas communication options such as eSIM and SIM cards have diversified, Wi-Fi rental continues to be in high demand for corporations due to reasons such as "simultaneous connection of multiple devices is possible," "no device setup required," and "easy centralization of expense settlement and usage management." To meet these specific corporate communication needs, the Company launched its 5G Unlimited Plan in May 2025.

To accommodate the diversification of overseas business trip destinations and the expansion of corporate global operations, 42 new countries and regions, including the Middle East/Gulf region (e.g., UAE, Saudi Arabia), Africa (e.g., Kenya, Nigeria), and South America (e.g., Brazil, Argentina), will be added starting July 2 (Thu). This will allow for more detailed coverage of various business scenarios, such as overseas business trips, project promotion with overseas bases, travel to factories and construction sites, on-site inspections, and participation in international conferences. High-speed communication required for tasks such as high-definition online meetings, cloud services, and large data transmission/reception can also be used comfortably without worrying about communication capacity. Furthermore, corporate clients with multiple travel destinations can consolidate their Wi-Fi equipment arrangements with a single provider, making it easier to centralize management costs, settlement operations, and support contacts with Telecom Square.

Going forward, in addition to expanding coverage areas, the Company will continue to improve service quality by continuously monitoring service availability and communication quality in cooperation with partner telecommunications carriers, and further enhance its 24/7 Japanese language support system. We will also strive to create an environment that reduces the burden of choosing communication services for each overseas business trip destination, aiming to be a company that customers can rely on by consulting "Wi-Ho!Biz first" while combining optimal communication methods such as Wi-Fi rental, eSIM, and SIM cards.

<Comment from CEO Tamura>

Overseas communication options are diversifying, including eSIM, SIM cards, and Wi-Fi rental. However, what corporate clients seek is not the communication method itself, but "the peace of mind of being connected no matter where they travel for business."

In corporations, needs such as reducing individual setup burdens, using multiple devices simultaneously, and standardizing communication methods for travelers are increasing year by year. Therefore, we believe that Wi-Fi rental, alongside eSIM, is one of the important communication solutions that cater to the usage scenarios of our corporate clients.

The background to expanding the 5G Unlimited Plan to an industry-leading 81 countries and regions is our aim to become the go-to choice for customers when considering overseas communication, with the idea that "you can count on Wi-Ho!Biz first."

Going forward, we want to continue to be a company that provides the optimal overseas communication environment for our customers, rather than focusing on the differences between communication methods such as Wi-Fi rental, eSIM, and SIM cards.
