Stellar eSim eSIM Data Plans for Japan

Stellar eSim does not provide a true unlimited high‑speed data eSIM for Japan. Plans that use “Unlimited” in their name actually contain a fixed data allowance and are not genuinely unlimited.
Travelers who need large data amounts can choose one of Stellar’s fixed data plans, such as the Japan 100GB 60‑day plan for $26.67 USD or the Japan 50GB 30‑day plan for $17.41 USD. These plans offer a set amount of data that can be used freely within the specified validity period.

Stellar eSim does not provide an eSIM with a local phone number or SMS capability for Japan. Only data‑only plans are available. Travelers who need voice or SMS can use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, though access to these apps can sometimes be restricted by local regulations. It is advisable to confirm that the messaging or calling apps you rely on work in Japan before purchasing a Stellar eSim plan.

Stellar eSim provides 95 single‑country data plans dedicated to travelers in Japan and 214 multi‑country plans that include Japan as one of the covered destinations. The available plans vary in data cap from 100 MB up to 100 GB, and a typical range of prices runs from approximately $0.68 to $2, 680.16 USD, depending on the chosen data amount, validity period, and whether the plan is single‑country or covers multiple markets.
