Sim Local eSIM Data Plans for Japan

Sim Local does not offer a truly unlimited high‑speed data eSIM for Japan. The plans that carry the “Unlimited” name—such as Japan Unlimited – 4 Day, Japan Unlimited – 7 Day, and Japan Unlimited – 10 Day—each provide 10GB of high‑speed data each day. Once that daily amount is reached the speed is throttled, so the plan is not unlimited in the sense of uninterrupted high‑speed data.

If a user needs a larger data allowance, Sim Local offers fixed‑data plans as alternatives. For example, the Asia 20 GB plan provides 20GB of data for 31 days, and the Orange Holiday World 20 GB plan also gives 20GB for 31 days, both available for use in Japan and additional destinations. Choosing a fixed‑data plan may be more cost‑effective for travelers who are not extremely heavy data users.

Sim Local does not provide a Japan eSIM that includes a local phone number or SMS capability. The available Japan plans from this provider are data‑only, so travelers cannot place traditional voice calls or receive text messages via a local number. They can still use internet‑based messaging and voice services such as WhatsApp, Telegram, or iMessage over the data connection.

Sim Local offers four single‑country data plans for Japan and an equal number of multi‑country plans that include Japan among other destinations. The available plans span a price range from $4.00 to $39.00 and include data caps between 500 MB and 20 GB. Duration options vary from 1 to 31 days. Within both categories, plans are split into daily data‑cap options—where the data allowance refreshes each day—and fixed data‑cap choices that provide a total amount of data for the whole validity period.
