GulfData eSIM Data Plans for South Korea

GulfData does not offer a truly unlimited high‑speed data plan for South Korea. All of GulfData’s South Korea plans list a specific data cap, even those with “Unlimited” in the name; after the allotted data is used, the speed drops to 512 kbps. For travelers who want a large amount of high‑speed data, fixed data plans are available, such as the 50 GB 30‑day plan priced at $34.00 USD or the 20 GB 30‑day plan for $16.50 USD. These fixed plans provide a clear data allowance within a set validity period and can be a more cost‑effective option unless a user requires a very heavy data usage.

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.
