1 GB or straight to 10 GB
The gap between the two is $16.20. For 2-3 days of maps and messaging, 1 GB for $3 may do. For a week with photos, video and calls, 1 GB is almost certainly too little, and there is nothing in between.
Yesim's Korea page contradicts itself on top-ups, so do not count on adding data. If in doubt, take 10 GB. The site calculator also shows a 1-day plan for $4.20, but that costs more than 1 GB for 30 days.
When to buy
You must activate a Korea eSIM within 90 days of purchase, not 180 as with Armenia. The 30 days start when you connect. Hotspot is available, so you can share data with a laptop.
Also worth knowing
- Data only: no calls, no SMS, no Korean number.
- Speed may be limited under the operator's fair usage policy.
- No ID check, and one QR code installs on one phone. Dial *#06# to check eSIM support: the reply should include an EID line.
- yesim.app accepts Visa, Mastercard, Apple Pay, Google Pay, PayPal and UnionPay. Promo code travelpayouts24 gives new users 3 EUR off, under the affiliate programme terms.
