Sim Local eSIM Data Plans for Japan

Sim Local does not provide a truly unlimited data eSIM for Japan. All of its “Unlimited”‑named plans actually cap the data at 10 GB per day and do not offer high‑speed data beyond that limit. Travelers who need more data without a daily limit can choose from the provider’s fixed‑data options, such as the Japan 20 GB plan that gives 20 GB for 30 days, or the Orange Holiday World 20 GB plan with 20 GB valid for 31 days. These larger fixed plans can be more economical for heavy‑data users who would otherwise hit the daily cap on the “Unlimited” name plans.

Sim Local does not offer eSIM plans for Japan that include a phone number or SMS capability. All available Japan eSIMs from Sim Local are data‑only and do not provide inbound or outbound calls or text messages.

Travelers who need messaging or calling can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which function without a local phone number.

Sim Local offers 8 single‑country plans covering Japan and 3 multi‑country plans that include Japan. The single‑country tickets are available in both fixed data‑cap and daily‑cap varieties; a fixed‑cap plan provides a set amount of data for the whole validity period, while a daily‑cap plan offers the same amount of data each day. Prices run from roughly $6.75 to $88.25, with data caps from 1 GB up to 20 GB, and validity spans 1 to 31 days.
