These additions enable us to meet a wide range of needs, from short vacations to study abroad programs, business trips, and workations.

Overview of the Expanded Product Lineup
In recent years, international travel has become increasingly diverse. In addition to leisure travel and business trips, more people are studying abroad, undertaking long-term overseas assignments, or working remotely while traveling. At the same time, demand for high-volume data has increased due to activities such as video streaming, social media use, online meetings, and cloud-based business applications.
To address these evolving needs and prepare for the upcoming summer travel season, including summer vacations and the Obon holiday period, eSIM square has expanded its product lineup.
This expansion focuses on popular destinations such as Taiwan, China, Thailand, and Italy, with the addition of 144 unlimited-data plans across 25 countries and regions, allowing travelers to stay connected without worrying about data usage limits.
Furthermore, to support customers traveling for longer periods, including students studying abroad, business travelers on extended assignments, and remote workers, we have added 82 plans valid for 30 days or more across 41 countries and regions.
As a result, customers can now choose the most suitable plan for their specific travel needs, whether for short-term trips or long-term stays.

What is an eSIM?
An eSIM (embedded SIM) is a digital SIM that is built directly into a smartphone or device. After purchasing a plan, users can complete the setup process in advance using a QR code provided to them. Once they arrive at their destination, they simply switch their device settings to begin using mobile data.
Compared with Wi-Fi rental services or physical SIM cards, eSIMs eliminate the need to visit a store, reduce the amount of travel gear users need to carry, and generally offer a more affordable and convenient way to stay connected while abroad.
