I didn't buy it in the end since the price with a discount was zero, but when clicking the activation button, it was asking for a 0.5 EUR payment with no description for the purpose of that extra hidden cost.

Frequently Asked Questions

Does Yesim offer unlimited data eSIM for Japan?

Yesim offers unlimited data eSIM plans for Japan that are available for 1 day, 7 days, 10 days, 15 days, and 30 days of validity, with prices ranging from $8.13 USD for the 1‑day plan to $73.13 USD for the 30‑day plan. All unlimited plans support tethering and provide coverage on 3G, 5G, and LTE networks throughout Japan.

Because the plans are marked as unlimited, a Fair Usage Policy applies; speeds may be throttled after heavy usage. Travelers who are concerned about potential speed restrictions should contact Yesim directly to confirm how long normal speed is maintained and what typical data allowance remains before throttling.

Does Yesim offer Japan eSIM with phone number and SMS?

Yesim does not offer eSIM plans with a phone number or SMS capability for Japan. All eSIMs available from Yesim for Japan are data‑only, so travelers must rely on VoIP applications such as WhatsApp, Telegram and iMessage for voice calls and text messaging over the data connection.

How many data plans does Yesim offer for Japan?

Yesim provides both single‑country and multi‑country eSIM options that include Japan. In total, there are 8 plans that cover only Japan and 13 plans that include Japan as part of a broader regional bundle. The single‑country plans range in price from about $8.13 to $26.49 for data caps from 3 GB to 10 GB, while the multi‑country plans cover Japan within bundles priced between roughly $15.54 and $126.53, offering data caps that span from 3 GB up to unlimited. The ranges in validity also vary from a single day to an entire year, and most plans allow tethering; speeds may be throttled on higher‑volume or longer‑term offers.
