MobiMatter eSIM Data Plans for Japan

MobiMatter does not provide an unlimited‑data eSIM plan for Japan. Instead, the company offers fixed data options, such as a 60‑GB plan valid for 90 days at $45.99 USD and a 50‑GB plan valid for 30 days at $29.99 USD. Choosing a fixed‑data plan can be more cost‑effective unless a traveler requires an exceptionally high data volume.

MobiMatter does not offer a Japan eSIM that includes a local phone number or SMS capability. The provider’s Japan plans are data‑only, so travelers who require a physical phone number must use other services. Calls and messaging can instead be carried out through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

MobiMatter provides 19 single‑country plans that cover Japan and 33 multi‑country plans that include Japan as part of a broader coverage package. The available plans span a price range from $3.99 to $74.99 and offer data capacities between 1 GB and 60 GB. Some plans deliver a fixed data allotment for the entire validity period while others apply a daily data cap, allowing users to choose a model that best matches their usage pattern.
