Instabridge eSIM Data Plans for Japan

Instabridge does not provide an unlimited data e plan for Japan. Travelers can choose fixed‑data options, such as the 20 GB Japan eSIM Mobile Data Plan valid for 7 days at $24.00 USD or the 10 GB Japan eSIM Mobile Data Plan valid for 30 days at $16.00 USD. These high‑capacity plans are typically more cost‑effective for most users unless they are heavy data consumers who would need an unlimited plan.

Instabridge does not offer a Japan eSIM plan that includes a phone number or SMS capability. The provider only offers data‑only eSIMs for Japan; travelers can use the data connection for VoIP applications such as WhatsApp, Telegram, and iMessage to make calls and send messages.

Instabridge currently offers 4 single-country data plans specifically for Japan, providing coverage solely within the country. Additionally, they list 8 multi-country plans that include Japan as part of a broader regional or global coverage area.
