Sim Local eSIM Data Plans for Japan

Sim Local does not offer a true unlimited data eSIM for Japan.
The plans listed as “Japan Unlimited” provide a maximum of 10GB per day, which is a capped amount of high‑speed data; after that limit is met the speed can be reduced, so the name does not reflect unlimited usage.

Instead, Sim Local offers fixed‑data eSIMs as alternatives. For example, the Orange Holiday World plan provides 20GB for 31 days at $35, and the Asia 20GB plan gives 20GB for 31 days for the same price. These fixed‑data options can be more cost‑effective unless a traveler requires extensive data beyond the capped daily allowance.

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.

In Japan, Sim Local provides five single‑country data plans and four multi‑country plans. Within those offerings there are five daily data cap options that reset every day and four fixed data cap options that are valid for the entire period. Prices range from roughly $4.00 to $77.50, and the data limits span from 500 MB up to 20 GB.
