Frequently asked questions
Is YonoSIM always cheaper than Airalo?
Not always. YonoSIM sources plans from a wholesale partner, and sometimes the lowest plan for a given country is cheaper, sometimes Airalo's is. The /plans page sorts by total price so you can verify before you buy.
Can I pay with KakaoPay or NaverPay?
Yes — YonoSIM supports KakaoPay, NaverPay, TossPay, and Korean-issued cards via PortOne, billed in KRW. Airalo currently bills in USD via international card networks only.
Does YonoSIM offer Korean support?
Yes. Chat and email support is available in both Korean and English, typically responding within ~1 business hour during Asia-Pacific waking hours.
Can I keep the same eSIM and top up later?
On most plans, yes — top-ups attach to the same eSIM profile so you don't need to scan a new QR. Check the plan detail page for the explicit top-up flag.
