Stellar eSim eSIM Data Plans for Japan

Stellar eSim does not provide an unlimited data eSIM plan for Japan. All of its available Japan plans feature a fixed data allowance; for example, a 50GB plan valid for 30 days costs about $12.94 USD, and a 50GB plan valid for 180 days costs around $21.34 USD. If a traveler needs more data than these fixed limits, they may choose a higher‑cap plan or a longer validity period. For users who consume very large amounts of data, a fixed plan can be more cost‑effective than paying for additional data on a pay‑as‑you‑go basis, but there is no unlimited option available.

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 supplies 43 single‑country data plans and 52 multi‑country data plans for Japan. The options span a price range from roughly $0.79 to $103.82 and offer data caps between 100 MB and 50 GB, with validity periods ranging from 1 to 365 days.
