“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 does not provide a truly unlimited high‑speed data plan for South Korea. The plans that carry the word “UNLIMITED” in their names are actually capped at 5 GB per day for up to 30 days, or at 30 GB for 30 days or 30 GB per month for 90 days; after the cap is reached the speed drops to a reduced rate (1 kbps or 1024 kbps). For travelers who need a larger data allowance without a hard daily limit, Saily offers fixed‑data options such as the South Korea 20 GB 30‑day plan for $29.99 USD and the South Korea 5 GB/day plan for 30 days at $71.99 USD. Choosing a fixed‑data plan can be more cost‑effective unless a user requires very heavy data usage.
Saily does not offer South Korea eSIM plans that include a phone number or SMS capability. Only data‑only eSIM plans are available. Travelers who need to send or receive text or make voice calls can rely on third‑party messaging and calling apps such as WhatsApp, Telegram, or iMessage, which operate over the data connection.
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.
