Instabridge eSIM Data Plans for Japan

Instabridge does not provide an unlimited data eSIM for Japan.
The provider offers fixed‑data plans, such as the 20 GB Japan eSIM Mobile Data Plan, which is valid for 7 days and costs $24.00 USD, and the 10 GB Japan eSIM Mobile Data Plan, valid for 30 days and priced at $16.00 USD. These fixed‑data options can be more cost‑effective for most travelers, unless the user expects to consume very large amounts of data.

Instabridge does not provide a Japan eSIM that includes a phone number or SMS capability. The provider offers only data‑only packages for Japan. Travelers can still use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice and messaging.

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. These plans vary, with options for both fixed data amounts (like 1GB, 5GB, or 20GB) and plans offering data usage over a set number of days. Prices range from approximately $2.50 to $68.00, and data caps range from 1GB to 20GB.
