ETravelSim eSIM Data Plans for South Korea

ETravelSim does not provide a truly unlimited data eSIM for South Korea. The plans that carry the word “Unlimited” actually give users 4 GB per day and, once that daily allowance is exhausted, the connection speed drops to 128 kbps. This means the high‑speed data is still capped, just advertised with an unlimited name.

If you need a fixed‑data option, ETravelSim offers plans such as 50 GB for 30 days at $49.99 USD or 25 GB for 30 days at $27.50 USD, which provide larger data allowances and avoid speed throttling. These fixed‑data plans may be more cost effective for most travelers unless you are an exceptionally heavy data user.

ETravelSim does not provide any South Korea eSIM plans that include a local phone number or SMS functionality. All South Korea eSIMs sold by ETravelSim are data‑only. Travelers can still use VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging.

ETravelSim offers 10 single‑country data plans and 8 multi‑country data plans for South Korea. Prices span from $4.50 to $109.99 and data caps range from 1 GB to 50 GB, with validity periods from 5 to 365 days. Users can select between daily data cap plans (4 options) and fixed data cap plans (14 options). Some plans may apply a reduced speed clause.
