MobiMatter eSIM Data Plans for Japan

MobiMatter does not provide an unlimited data eSIM for Japan. The provider’s products for Japan use fixed data allowances. For example, a 60GB plan that is valid for 90 days costs $45.99 USD, while several 50GB plans that are valid for 30 days are priced between $29.99 USD and $32.99 USD. These fixed plans can be more cost‑effective for travelers who are not extremely heavy data consumers.

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 23 single‑country data plans that are limited to Japan and 42 multi‑country plans that can be used in Japan as well as other destinations. The single‑country plans normally feature fixed data amounts that cover the entire validity period, while the multi‑country plans also come with daily data caps to aid in multi‑day travel. Across all Japan offerings the prices range from roughly $3.99 to $74.99, and the data caps span from 1 GB up to 60 GB.
