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, available in five validity options: 1 day, 7 days, 10 days, 15 days and 30 days. The prices range from $8.21 for the 1‑day plan up to $73.92 for the 30‑day plan, and all plans include tethering.
Because these plans are marked "unlimited," a Fair Usage Policy applies: after heavy use speeds may be throttled. If you need clarification about how much data is available at full speed or want to confirm the exact FUP thresholds, contact Yesim directly before purchasing.
Does Yesim offer Japan eSIM with phone number and SMS?
