AloOui eSIM Data Plans for South Korea

AloOui does not offer a genuinely unlimited data eSIM plan for South Korea. The plans branded “Unlimited Lite, Unlimited Essential, and Unlimited Plus” provide only 1 GB or 2 GB of high‑speed data per day; once the cap is reached the speed is reduced to 512 kbps, 1.25 Mbps, or 2 Mbps, so they are not true unlimited high‑speed plans.

Instead, AloOui offers several fixed‑data options that may be more suitable for travelers requiring large amounts of data. For example, the 100GB 30‑day plan is priced at $223.67 USD, while a 100GB 90‑day plan costs $278.82 USD; there are also other 100GB packages at comparable prices. These fixed‑data plans can be more cost effective for users who anticipate heavy data usage, whereas the “Unlimited” entries may only suit light to moderate consumption.

AloOui does not provide South Korea eSIM plans that include a local phone number or SMS capability. All of their South Korea offerings are data‑only, so travelers will need to rely on internet‑based messaging and calling services. VoIP applications such as WhatsApp, Telegram and iMessage can normally be used over the data connection for voice and text, but users should verify that these services are accessible in South Korea before purchasing, as some destinations may restrict certain apps.

AloOui lists 29 single‑country data plans that cover South Korea and 64 multi‑country plans that include South Korea among their destinations. The single‑country plans range in price from $5.95 up to $493.26 and offer data caps between 1 GB and 100 GB, with validity periods spanning 1 to 180 days. Multi‑country plans have similar pricing and data ranges, providing both daily‑cap and fixed‑data options. The overall catalog thus offers a wide spread of price points and data volumes for travelers heading to South Korea.
