Stellar eSim eSIM Data Plans for Japan

Stellar eSim does not offer an unlimited‑data eSIM for Japan. All available plans specify a finite data cap, such as 50 GB or 20 GB for periods ranging from 30 days to 180 days.

Travelers who need larger data allowances can choose a fixed‑data plan from Stellar eSim, for example a 50 GB plan valid for 30 days or a 50 GB plan valid for 180 days. These fixed plans may provide better value for moderate or heavy data use and are often more cost‑effective than a truly unlimited option.

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.
