Ozly eSIM eSIM Data Plans for Japan

Ozly eSIM does not provide an unlimited data eSIM for Japan.
Instead, Ozly eSIM offers several fixed‑data plans that cover Japan. For example, the Japan 50GB 30Days plan gives 50GB of high‑speed 5G data for 30 days, and the Japan 20GB 30Days plan provides 20GB for the same validity period. A longer‑term option that includes Japan is the Asia‑20 50GB 180Days plan, which offers 50GB of 5G data for 180 days and covers Japan plus 16 additional countries. Fixed data plans can be a more cost‑effective choice for most travelers, unless one requires truly unlimited usage.

Ozly eSIM does not provide a Japan eSIM with a temporary phone number or SMS capability. The only Japanese eSIMs offered by Ozly eSIM are data‑only plans.

Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage to send messages or make calls over the data connection, as these services work without a local phone number or SMS capability.

Ozly eSIM provides a total of 6 single‑country plans and 52 multi‑country plans that cover Japan. The single‑country options are priced between about $1.65 and $8.00, with data caps ranging from 500 MB to 5 GB, while the multi‑country plans are available from roughly $9.00 up to $171.20, offering data caps from 1 GB to 50 GB. Plans vary in that some give a fixed data amount for the entire validity period, whereas others impose daily data limits that can be useful for users who consume data intermittently. All plans have validity periods ranging from one day to one year, and many allow tethering for sharing connectivity across devices.
