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 that cover Japan. The plans start at a 1‑day “Asia Pacific” option for $13.96 USD, and continue with 7‑, 10‑, 15‑, and 30‑day “Japan” plans ranging in price from $24.43 USD to $73.30 USD. All these plans advertise unlimited data, allow tethering, and note that speeds may be throttled after heavy usage. Speed throttling is a form of the Fair Usage Policy (FUP), so users who want guaranteed high‑speed data at all times should contact Yesim directly to confirm whether FUP applies and the typical amount of data available at normal speed.

Does Yesim offer Japan eSIM with phone number and SMS?

Yesim does not provide a Japan eSIM that includes a phone number or the ability to send or receive SMS messages. The available plans are data‑only eSIMs that can be used for internet connectivity while you travel in Japan.

Users who need voice or text communication can rely on popular VoIP applications such as WhatsApp, Telegram, and iMessage, which operate over the data connection and do not require a local phone number or SMS capability.

How many data plans does Yesim offer for Japan?

Yesim offers seven single‑country plans for Japan and thirteen multi‑country plans that include Japan. The single‑country options range from 3 GB to unlimited data, with validity periods from 1 to 365 days, and similarly for the multi‑country bundle range. Prices start around $13.96 and go up to $126.82, depending on the data cap and validity length. Among these plans, a few provide a fixed data amount, while others deliver a daily data capacity, allowing users to choose the style that best matches their usage habits.
