GulfData eSIM Data Plans for South Korea

GulfData does not offer a truly unlimited high‑speed data eSIM for South Korea. The plans that carry “Unlimited” in their name give 1GB of high‑speed data; once that 1GB is used, the speed drops to 512 kbps.

For travelers who need more data, GulfData sells fixed‑data plans. For example, a 20GB plan for 30 days costs $16.50 USD, and a 50GB plan for 30 days costs $34.00 USD. These plans provide the specified high‑speed data without the throttling that occurs on the “Unlimited” plans.

GulfData does not provide eSIM plans that include a phone number or SMS capability for South Korea. Only data‑only plans are available from the provider.

Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging. However, some destinations may block or restrict access to certain apps or VoIP services, so users should confirm that the applications they rely on work in South Korea before buying a plan.

GulfData offers 12 single‑country data plans and 43 multi‑country plans that include South Korea. The plans are priced between $3.00 and $197.50 and provide data caps ranging from 1 GB to 50 GB, with validity periods from one to 365 days. Fixed‑data‑cap plans give a set amount of data for the whole validity period, while daily‑data‑cap plans reset the data allowance each day.
