Sim Local eSIM Data Plans for Japan

Sim Local does not provide a truly unlimited high‑speed data eSIM plan for Japan. Every plan that carries the word “Unlimited” in its name actually offers a capped amount of data – in this case 10 GB of high‑speed data per day, after which the connection would be throttled to a lower speed.

If a traveler needs more data or wants a plan that is not rate‑limited after a certain amount, Sim Local does sell fixed‑data options. For example, the Asia 20 GB plan delivers 20 GB of high‑speed data for 31 days at $35 USD, and the Orange Holiday World 20 GB plan provides the same data and validity for 31 days at the same price. These fixed‑data plans can be more cost‑effective for heavy users compared to buying several of the “Unlimited” day packages.

Sim Local does not provide a phone number or SMS service for Japan. All of its Japan eSIM plans are data‑only, so there is no way to receive or send text messages or make calls directly through a local mobile number. Travelers can still use the data connection to access VoIP services such as WhatsApp, Telegram, and iMessage for calls and messaging.

Sim Local provides a total of five single‑country data plans exclusively for Japan, and four multi‑country plans that cover Japan along with other destinations. The price range across these options spans from roughly $4 to $77.50, while the data caps vary between 500 MB and 20 GB. Providers offer both daily data‑cap plans—where the data allowance resets each day—and fixed data‑cap plans, which give a one‑time total amount of data for the entire validity period.
