thirr.com does not offer an unlimited data eSIM plan for Japan. All of the plans listed on the provider’s site for the destination have a set data cap, the largest of which is a 100GB allowance. For travelers who need high data volumes, thirr.com provides several fixed‑data options that could be more cost‑effective. For example, the XXL World 100GB 31D plan offers 100GB of data for 31 days at a price of $76.19 USD, and the JP 50GB 30D plan gives 50GB for 30 days for $18.05 USD. These plans include 5G connectivity and cover Japan (with the XXL World plans also covering additional countries). Selecting a fixed data plan may be a better fit for heavy users than a pay‑as‑you‑go option, but thirr.com does not provide any unlimited data eSIM for Japan.
Thirr.com does not provide an eSIM that includes a phone number or SMS capability for Japan. All plans for Japan from thirr.com are data‑only; travelers who need voice or text can rely on internet‑based services such as WhatsApp, Telegram, or iMessage over the data connection.
An examination of the list of plans from thirr.com shows that, for Japan, there are 4 single‑country plans and 18 multi‑country plans that include Japan among their coverage areas.
