GIGAGO eSIM Data Plans for Japan

GIGAGO does not offer an unlimited data eSIM plan for Japan. All available plans have a fixed data cap.

GIGAGO’s fixed data options include a 50 GB plan valid for 5 days priced at $67.50 USD, a 50 GB plan valid for 30 days priced at $77.50 USD, and a 20 GB plan valid for 5 days priced at $27.50 USD. Selecting a fixed data plan can be more cost‑effective for most travelers unless a very heavy data usage is required.

GIGAGO does not provide any Japan eSIM that includes a phone number or SMS capability. Only data‑only plans are offered for Japan, so travelers cannot receive inbound calls or standard text messages on the local network.

Because a phone number is not assigned, travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging needs. These solutions work without requiring a local Japanese phone number.

GIGAGO lists 28 single‑country data plans for Japan and 42 multi‑country plans that include Japan within a broader itinerary. Prices for these plans range from roughly $7.50 to $94.50 USD, and data caps span from 500 MB up to 50 GB over validity periods of 3 to 30 days. Some offerings are fixed‑data plans, providing a set amount of data for the entire validity, while others are daily‑cap plans that reset each day, allowing a maximum data usage per day. These options give travelers flexibility for both short visits and longer stays.
