Movisim eSIM Data Plans for Japan

Movisim does not provide a truly unlimited data eSIM for Japan; every plan that carries the word “Unlimited” in its title still includes a fixed data allowance, such as 1GB, 2GB, 5GB or 10GB, after which the connection speed is throttled to a reduced rate (e.g., 256kbps, 384kbps, 512kbps or 1000kbps).

The provider offers fixed‑data plans that can be more economical for typical travelers. For example, a 10GB 1‑day eSIM is available for $8.99 USD with a reduced speed of 384kbps after the 10GB limit, and a 50GB 30‑day plan can be purchased for $30.99 USD with no reduced speed specification. These fixed‑data options give high‑speed access up to the set data cap without the unlimited label.

Movisim does not offer a Japan eSIM that includes a local phone number or SMS capability. Their Japan plans are limited to data‑only usage. Travelers who need voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though some destinations may restrict access to specific apps or services, so it is advisable to confirm that the apps they rely on are available in Japan before purchasing a Movisim plan.

Movisim lists a total of 79 single‑country plans and 97 multi‑country plans. These cover prices from $2.99 to $120.99, data caps ranging from 100 MB up to 50 GB, and validity periods from 1 to 365 days. The summary does not specify how many of these plans are specifically for Japan.
