BlueSky eSIM eSIM Data Plans for South Korea

BlueSky eSIM does not provide a truly unlimited high‑speed data plan for South Korea. Their plans that appear as “Unlimited” restrict data to 3GB each day; once that daily limit is reached, the speed drops to a reduced rate of 1000kbps.

For travelers who require a larger, unthrottled data allowance, fixed‑data plans are available. For example, a 20GB/30d plan costs $30, and a larger 100GB/180d plan is offered for $89. These options give continuous high‑speed data without the daily cap seen on the so‑called unlimited packages.

BlueSky eSIM does not provide a South Korea eSIM plan with a phone number or SMS capability. All South Korea plans from BlueSky eSIM are data‑only; they give internet access but no inbound or outbound voice or text services. Travelers can still use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

BlueSky eSIM offers a total of 41 data plans that include South Korea. This set is split into 11 single‑country plans that are exclusively valid in South Korea and 30 multi‑country plans that cover South Korea in addition to other destinations.

The plans range in price from $1.97 to $89.00 and in data cap from 200 MB up to 100 GB. Validity periods vary from 3 days to 365 days. Within these plans, there are two primary types: 31 plans with a fixed data amount and 10 plans that impose a daily data cap. Fixed data plans provide a set quantity of data that can be used at any point during the validity, while daily cap plans reset the data allowance each day, allowing a new amount of data to be used daily throughout the period.
