Movisim eSIM Data Plans for Japan

Movisim does not currently provide a truly unlimited high‑speed data eSIM for Japan.
All of its Japan plans that use “Unlimited” in the name have a fixed data allowance – for example, the 2GB, 3GB, and 10GB one‑day plans. Once that amount is used, speed is throttled to the reduced speed specified in the plan’s details.

For travelers who need a larger amount of high‑speed data without a daily cap, Movisim offers fixed‑data plans such as the Japan 50GB – 30‑Day eSIM or the Japan 10GB – 1‑Day eSIM, which provide a substantial data pool that can be consumed over the plan’s validity period.

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 44 single‑country data plans exclusively for Japan and 58 multi‑country packages that also cover Japan. Prices range from $2.99 to $163.99, with data caps spanning 100 MB up to 50 GB and validity periods between one and 365 days. Most plans provide a fixed data amount for the entire validity period, while a few offer daily‑reset pockets of data that refresh each day.
