thirr.com eSIM Data Plans for Japan

Thirr.com does not provide an unlimited data eSIM for Japan, and every plan listed carries a specific data cap. The largest cap available is 50 GB for 30 days.

For travelers who need a fixed data plan, thirr.com offers options such as the JP 50GB 30D plan priced at $19.97 USD or the JP 20GB 30D plan for $9.16 USD. These plans give a generous amount of high‑speed data, but users with extremely heavy data needs may find a larger or longer‑validity plan more cost‑effective.

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 provides a combination of single‑country options and multi‑country packages for travelers heading to Japan. There are three distinct single‑country plans that cover only Japan, while sixteen multi‑country plans are available for users that plan to visit several destinations in a single subscription. The single‑country plans usually offer a fixed data allotment for a set validity period, whereas the multi‑country plans often combine a data cap that can be shared across multiple regions, with the daily usage limits varying by package. Across all plans, the price ranges from as little as about $2.22 to nearly $354, and the data limits span from 1 GB up to 50 GB, with validity terms that can extend from 3 days to an entire year. Many of the plans also allow tethering, giving additional flexibility for device sharing.
