“Installation, price, set up was as easy as you can get. However, the speed in South Korea was abysmal (I had better experience in other country).
Usually slow but usable, but at times you opened Google Maps and it wouldn't even finish loading your "pins". So stressful to use, up to the point that one friend with the same SIM got himself a different one during the trip and I hopped Free Wi-Fis. Not what I bought this SIM for!”
Saily’s plans that carry the “UNLIMITED” name for South Korea are not truly unlimited high‑speed data plans. Each of those plans has a hard limit of 5 GB per day, and once that limit is reached the connection speed is throttled to 1 kbps. The “UNLIMITED” designation is therefore a marketing label rather than a permanent data allowance.
For travelers who need more data, Saily offers fixed‑data plans such as the 20 GB for 30 days plan and the 25 GB for 60 days plan. These plans provide a set amount of high‑speed data that must be used within the given validity period, but they can be more cost‑effective for users with higher data needs.
Saily does not provide a South Korea eSIM that includes a phone number or SMS capability; the provider only offers data‑only eSIMs for that destination. Travelers who wish to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that those services are accessible in South Korea before purchasing.
Saily offers 11 single‑country and 22 multi‑country data plans for South Korea. The plans include daily data‑cap options as well as fixed‑data‑cap packages; daily caps provide a set amount of data that can be used each day, while fixed caps allow a total amount that can be consumed over the entire validity period. Prices for the South‑Korean plans range from about $3.99 to $159.99, and the data caps cover from 1 GB up to 30 GB, with validity periods that can last between 5 and 365 days.
