Stellar eSim does not provide a truly unlimited data eSIM for Japan. The plans that carry the word “Unlimited” in their names actually have hard data caps of 1 GB or 3 GB for the validity period, and after the cap is reached the speed may be reduced.
Travelers who need more data can choose from Stellar eSim’s fixed data plans, such as the Japan 100 GB 60 days plan or the Japan 50 GB 30 days plan. These plans offer larger data allowances for a set validity period and can be more cost‑effective for most users.
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 92 single‑country data plans that cover Japan alone, and 214 multi‑country data plans that include Japan in the roster. Prices across the portfolio vary from roughly $0.66 to $2, 713.26, while data caps range from 100 MB up to 100 GB, giving travelers flexible options depending on length of stay and data usage.
