Yesim eSIM Data Plans for Japan

Yesim offers unlimited data eSIM plans specifically for Japan. The provider lists a range of validity options from 1 day up to 30 days, and the prices for these unlimited plans vary accordingly, starting at about $8.07 USD for a 1‑day pass and reaching around $63.44 USD for a 30‑day plan. All of these plans include tethering allowance, and the network is 5G.

Because the plans are described as “unlimited, ” the term is subject to a fair‑usage policy. Speed may be throttled after a certain level of data consumption, so those who need consistent high speeds should contact Yesim directly to confirm how the policy is applied and what typical data rates remain at normal speed.

Yesim does not provide any eSIM plans that include a phone number or SMS for Japan. Only data‑only eSIM options are offered. Travelers can use internet‑based messaging and calling apps such as WhatsApp, Telegram, and iMessage over the data connection to communicate while in Japan.

Yesim offers 8 single‑country plans and 21 multi‑country plans that include coverage in Japan. Single‑country plans concentrate data usage exclusively within Japan and may be either fixed‑amount or daily‑cap, while multi‑country plans allow the same data to be used across several destinations that include Japan in the package. The available plans span a price range from about $8.07 to $125.73 and a data cap range from 5 GB up to unlimited.
