thirr.com eSIM Data Plans for Japan

thirr.com does not offer an unlimited data eSIM plan for Japan. Travelers can choose from fixed data plans, such as the JP 100GB 31D plan, which provides 100GB of data for 31 days at $70.82 USD, or the JP 50GB 30D plan, which offers 50GB of data for 30 days at $17.70 USD.

Opting for a fixed data plan is generally more cost‑effective for most users, unless a traveler expects to use data at a rate that would surpass the allowances of these plans.
