Sim Local eSIM Data Plans for Japan

Sim Local does not provide a truly unlimited data eSIM for Japan.
All plans that carry “Unlimited” in their name offer a fixed data allowance of 10GB per day, after which the speed is reduced; they are therefore capped high‑speed data rather than unbounded.
If a traveler needs a larger data pool, Sim Local offers fixed‑data alternatives such as the Asia 20 GB plan (20 GB for 31 days, $35 USD) or the Orange Holiday World 20 GB plan (20 GB for 31 days, $35 USD). These plans can be more cost‑effective than the per‑day capped options, especially for users who consume a lot of data.

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 provides five single‑country data plans for Japan, covering the entire country under various data limits and validity periods. In addition, there are four multi‑country plans that allow use in Japan along with other selected destinations around the world. The single‑country and multi‑country offerings together span a price range from about $4.00 to $77.50, with data caps between 500 MB and 20 GB and validity of 1 to 31 days. Some plans give a fixed total data allowance for the whole period, while others provide a daily data cap that resets each day—allowing users to choose a strategy that best fits their daily usage patterns.
