Airalo eSIM Data Plans for South Korea

Airalo does not provide a truly unlimited high‑speed data plan for South Korea. All plans listed as “Unlimited” give 3GB of high‑speed data each day and, after that daily limit is reached, the speed falls to 1000kbps (or 5000kbps for the LG U⁺ option).

Instead, travelers can choose fixed‑data plans that offer a large but capped amount of data. For example, Asialink‑100 GB is available for 180 days at $89.00, Asialink‑50 GB for 30 days at $59.00, and 짱 Jjang‑50 GB for 30 days at $49.00. These plans give more data upfront and do not have a daily cap, though once the allotted amount is used, no additional high‑speed data is provided unless another plan is purchased.

Airalo does not offer eSIM plans for South Korea that include a local phone number or SMS capability. Travelers can only purchase data‑only eSIMs for South Korea from Airalo. They can still use VoIP services such as WhatsApp, Telegram or iMessage over the data connection for calls and messaging, but no traditional voice or SMS service is provided.

Airalo lists 20 single‑country plans and 32 multiple‑country plans across its catalogue. The current dataset does not give a separate country‑specific breakdown, so the exact number of plans available specifically for South Korea is not stated. Across all plans Airalo’s prices range from about $4.00 to $89.00, and data caps vary from 1 GB up to 100 GB. The plans include both fixed‑data bundles and daily‑cap options, with some bundles offering reduced speed (0‑5000 kbps) for certain data amounts.
