Ovosim eSIM Data Plans for Japan

Ovosim does not provide a truly unlimited data eSIM for Japan. All of its Japan plans are fixed‑data packages, and each plan has a set maximum data allowance that is listed in the catalogue. For travelers who need large amounts of high‑speed data, Ovosim offers several high‑cap options; for example, the Japan Unlimited MAX 30 Days plan gives 150 GB for 31 days, while the Japan Unlimited STANDARD 30 Days plan offers 90 GB for the same period. Choosing a fixed data plan can be more cost‑effective unless the user expects to consume data at a volume far beyond the allocated cap.

Ovosim does not provide any Japan eSIM plan that includes a local phone number or SMS capability. All of the Japan eSIM offerings from Ovosim are data‑only plans. Travelers who need voice or text communication can rely on internet‑based VoIP apps such as WhatsApp, Telegram, or iMessage, which work over the data connection.

Ovosim lists 32 single‑country data plans that cover Japan, and 52 multi‑country plans that include Japan among their destinations. The plans range in price from about $5.18 to $115.40 and offer data amounts between 1 GB and 150 GB, with validity periods from 6 to 31 days. Most of the available plans provide a fixed data allowance rather than a daily data cap.
