Sim Local eSIM Data Plans for Japan

Sim Local does not provide a genuinely unlimited high‑speed data plan for Japan. The products named “Japan Unlimited” are capped at 10 GB per day and, once that amount is reached, the connection is throttled. Travelers looking for unrestricted data should consider one of Sim Local’s fixed‑data options. For example, a 20 GB plan that is valid for 30 days costs $93.75, while a 20 GB plan that covers 31 days for Japan and nearby countries is available for $35.00. These higher‑allowance plans offer a fixed data bundle that can be more cost‑effective for heavy‑usage travelers.

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 14 data plans for Japan, composed of 10 single‑country plans and 4 multi‑country plans. The plans vary in price from about $4.00 to $93.75 and in data allowance from 500 MB up to 20 GB, with validity periods ranging from one to thirty‑one days. Among the offerings there are both daily‑data‑cap plans—allowing a set amount of data each day—and fixed‑data‑cap plans, which provide a total data allotment over the plan’s duration.
