Roamly eSIM Data Plans for Japan

Roamly does not provide an unlimited data eSIM plan for Japan. The largest fixed bundle they offer is 50GB valid for 180 days, which already gives a generous amount of high‑speed 5G data. Other available fixed bundles include 20GB for 30 days and 10GB for 30 days. Travelers who need more than these amounts can purchase a larger bundle or combine multiple plans, and for heavy data users a fixed plan may be more cost‑effective than a pay‑as‑you‑go option.

Roamly does not provide a Japan eSIM that includes a phone number or SMS capability. The available plans are data‑only. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but some destinations may restrict these services, so it is advisable to verify that the apps you need work in Japan before purchasing.

Roamly provides a total of eleven distinct data plans for travelers in Japan, split into single‑country and multi‑country options. Five plans cover only Japan, while six plans include Japan as part of a broader regional package. The available plans range in price from about $3.81 to $77.65 and offer data caps between 3 GB and 50 GB, with validity periods spanning 15 to 180 days. Most of the plans are fixed‑data packages, meaning the data allowance is set for the entire validity period rather than being capped on a daily basis.
