aloSIM eSIM Data Plans for South Korea

aloSIM does not have an unlimited data plan for South Korea. The provider offers fixed‑data plans instead, such as a 100GB plan valid for 180 days or a 50GB plan for 90 days, both operating on 5G and covering South Korea. These larger data allowances can be more cost effective for travelers who use a lot of data, while more modest plans like 20GB or 10GB are also available if a smaller data budget is sufficient.

AloSIM does not provide South Korea eSIM plans that include a phone number or SMS capability. Travelers who purchase an aloSIM data‑only eSIM for South Korea can use the data connection with VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages. However, access to these services can depend on local restrictions, so users should check that the specific apps they need are available in South Korea before making a purchase.

aloSIM lists 12 single‑country plans and 19 multi‑country plans that are valid in South Korea. The single‑country options are dedicated to South Korea alone, while the multi‑country plans cover South Korea in addition to other destinations. The daily‑data‑cap plans number 12, offering a data allotment that resets each day, whereas the fixed‑data‑cap plans number 19, allowing the full data amount to be used over the validity period. Overall, the available packs range in price from about $4.50 to $185.00 and vary in data caps from 1 GB up to 100 GB, giving travelers a broad spectrum of choices.
