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‑coverage data plans for Japan and 33 multi‑coverage plans that include Japan in their itinerary. The single‑coverage options vary in price from roughly $3.99 to about $35, with data caps ranging from 1 GB to 30 GB. The multi‑coverage plans are priced between $35 and $74.99, offering data allowances between 5 GB and 60 GB, allowing users to pick a plan that best fits their travel or long‑stay needs. All plans use a fixed data amount rather than a daily cap, and many allow tethering for use with multiple devices.
