alodata eSIM Data Plans for South Korea

Alodata does not provide a truly unlimited data eSIM for South Korea. All of the plans that include “Unlimited” in their name offer only 1GB of high‑speed data, after which the speed is reduced to 1280kbps. The plans are therefore capped at a fixed amount of data rather than offering unlimited bandwidth.

For travelers who need more data, Alodata offers fixed‑data plans. For example, a 100GB plan is available for 30 days in South Korea at $230 USD, and a 100GB plan for 90 days in South Korea (and other Asian countries) is priced at $256 USD. These high‑cap plans can be more cost‑effective for users who consume a lot of data.

Alodata does not provide South Korea eSIM plans that include a phone number or SMS capability. Their South Korea offerings are data‑only, so travelers can use roaming data for internet access but cannot make regular voice calls or receive texts via a local number.

Instead, travelers can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging. These apps work well for communication while traveling, even without a local phone number or SMS support.

Alodata provides a selection of data plans for travelers to South Korea. In the single‑country category there are 15 plans that apply only to South Korea, while 40 multi‑country plans include South Korea as part of a broader network. The provider offers two main types of plans: fixed‑data‑cap plans, which give a set amount of data for a fixed validity period, and daily‑data‑cap plans, which reset a daily data allowance each day. Across the board prices range from about $5.00 to $320.00 and data caps vary from 1 GB to 100 GB.
