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 provides unlimited‑data eSIM plans for Japan, with validity options ranging from a single day to 30 days. The 1‑day plan costs 8.21 USD and the 30‑day plan costs 37.54 USD, giving travelers a price range for unlimited data usage. The plans are active on 3G, 5G, and LTE networks across Japan.
Because the unlimited plans carry a Fair Usage Policy, data speeds may be reduced after heavy usage, and normal speed could be capped at the provider’s maximum rate. If a traveler is concerned about potential speed restrictions, they should contact Yesim directly to confirm how the policy is applied and the typical amount of data available at full speed.
Does Yesim offer Japan eSIM with phone number and SMS?
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.
How many data plans does Yesim offer for Japan?
Yesim offers eight single‑country plans that cover Japan, together with an additional set of 20 multi‑country plans that include Japan among their destinations. The single‑country plans range in price from roughly $8.21 to $127.86 USD and provide data caps from 5 GB up to unlimited, while the multi‑country plans offer a broader spectrum of validity periods (from 1 to 365 days) and data caps within the same overall range. The fixed‑data plans deliver a set amount of data for the life of the plan, whereas the daily‑cap plans may reset the data allowance each day while still maintaining a total data ceiling.
