Sim Local eSIM Data Plans for Japan

Sim Local does not provide a truly unlimited high‑speed data eSIM for Japan. All plans that carry the word “Unlimited” in their name actually offer a fixed high‑speed allowance of 10 GB per day; once that quota is reached the speed is throttled. The provider also offers fixed‑data plans that give larger totals without a daily cap, such as the 20 GB plan valid for 31 days and the 20 GB “Orange Holiday World” plan also valid for 31 days. Choosing one of these fixed‑data options can be more cost effective unless a traveler expects to consume an extremely large amount of data.

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.
