Sim Local eSIM Data Plans for Japan

Sim Local does not provide a true unlimited data eSIM for Japan. The plans labeled “Unlimited” in the provider’s catalogue actually allocate a fixed amount of high‑speed data—10GB per day for the stated validity period. After the data allowance is used the service does not provide additional high‑speed data, so the plans are effectively fixed data plans rather than unlimited ones.

Travelers who need larger data volumes can choose from other fixed data plans offered by Sim Local. For example, the Japan eSIM – Unlimited Data for 4 Days plan gives 10GB per day for 4 days, while the Orange Holiday World 100 GB plan provides 100 GB for 31 days. These options allow users to select an appropriate data allowance for their stay in Japan.

Sim Local does not provide a Japan eSIM that includes a local phone number or SMS capability. Only data‑only plans are available for travelers to Japan. Users can still make and receive calls, as well as send and receive messages, by using popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that the specific apps they rely on work in Japan before purchasing.

Sim Local provides a choice of 10 single‑country data plans that cover Japan alone, and an additional 9 multi‑country plans that include Japan as one of several destinations. The plans cover a price range from about $4 to $93.50 and a data cap range from 1 GB up to 100 GB, with validity periods spanning 3 to 31 days. The catalog also distinguishes between daily data cap plans, where the data allowance resets each day, and fixed data cap plans, where a specified amount of data is available for the entire validity period.
