thirr.com eSIM Data Plans for Japan

No, thirr.com does not provide an unlimited data eSIM plan for Japan. The provider offers fixed‑data packages instead. For instance, the JP 50GB 30 day plan gives 50 GB of high‑speed data for $19.56 USD, and the HALFWORLD 50GB 365 day plan offers the same data allowance for $358.95 USD. Both plans allow tethering and cover 4G and 5G networks throughout Japan. Choosing a fixed‑data package can be more cost effective for most travelers unless they need to consume a very large amount of data.

No. thirr.com does not provide a Japan eSIM that includes a phone number or SMS capability. The provider offers only data‑only plans for Japan. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging, even without a local phone number.

thirr.com lists three single‑country plans for Japan and sixteen multi‑country plans that include Japan. The single‑country options cover data sizes from 1 GB up to 50 GB and are valid anywhere from 3 to 365 days, with prices ranging from about $2.49 to $358.95. The regional plans, which combine Japan with other countries, follow the same overall range of data caps and validity days, but offer a broader geographic coverage. Some plans deliver a fixed data allotment for the entire validity period, while others provide a daily data cap that limits usage on a per‑day basis.
