Yaalo eSIM Data Plans for South Korea

Yaalo does not provide a truly unlimited high‑speed eSIM plan for South Korea. All of the plans marketed as “Unlimited” give a daily data allotment of 1GB or 2GB; once that daily maximum is reached the speed drops to a reduced rate of 512kbps or 2000kbps. Travelers looking for high‑volume data may choose a fixed‑data option instead. For example, Yaalo’s 100GB eSIM plan for 30 days in South Korea costs $69.52 and its 100GB plan for 180 days in South Korea costs $120.12, offering a large data allowance without the throttling that applies to the “Unlimited” names. These fixed‑data plans can be more cost‑effective for heavy data users because the full data allowance is available at high speed throughout the validity period.

Yaalo does not provide eSIM plans with a phone number or SMS capability for South Korea. Only data‑only eSIMs are available for that country; VoIP applications such as WhatsApp, Telegram, or iMessage can be used for calling and messaging over the data connection.

Yaalo lists 31 single‑country data plans and 96 multi‑country plans that cover South Korea. The plans span a wide price range from about $1.35 to $358.12, with data caps that vary between 1 GB and 100 GB over validity periods from 1 to 180 days. The catalog includes both daily‑data‑cap options—offering users a fixed amount of data usable each day—and fixed‑data‑cap plans, which provide a total data allotment regardless of how many days they are active. Some plans also allow tethering, and a few feature reduced speed tiers of 512 kbps or 2000 kbps.
