Sim Local eSIM Data Plans for Japan

Sim Local does not offer an authentic unlimited data eSIM for Japan. All plans that include “Unlimited” in their name actually provide a fixed high‑speed allowance of 10GB per day, after which the connection speed is throttled. For travelers who need a higher data budget, Sim Local offers fixed‑data options such as the Asia 20 GB plan, valid for 31 days, and the Orange Holiday World 20 GB plan, also valid for 31 days. These fixed‑data plans give a larger amount of high‑speed data before any speed reduction occurs, which can be more cost‑effective for comparatively heavy data usage.

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, and five multi‑country bundles that include Japan among other destinations. The plans range from about $4 to $77.50 USD, and offer data caps from 500 MB up to 20 GB. Validity periods vary from a single day to a month, and the provider offers both fixed‑data‑amount bundles and daily‑cap options to suit different travel schedules.
