BambooSIM eSIM Data Plans for South Korea

BambooSIM offers a range of unlimited data eSIM plans for South Korea that can be used on 5G networks across the country. The plans start at $7.95 USD for a 1‑day valid period and go up to $131.95 USD for a 90‑day valid period, with intermediate options available for 2‑day, 3‑day, 4‑day, 5‑day, 6‑day, 7‑day, 8‑day, 9‑day, 10‑day, 15‑day, 20‑day, 30‑day, 60‑day, and 90‑day validity. All of these plans are labeled as unlimited data, allow tethering, and include a note that speeds may be throttled after extended use.

Because the plans are unlimited, BambooSIM applies a fair usage policy. Normal speed is generally provided up to the 5G peak rates, but after heavy usage, speeds may be reduced. Travelers who are concerned about potential speed restrictions should contact BambooSIM directly to confirm whether a fair usage policy applies on their chosen plan and to find out the typical amount of data that remains at normal speed before throttling.

BambooSIM does not offer any South Korea eSIM plan that includes a phone number or SMS capability; only data‑only plans are available. As a result, travelers cannot receive or send SMS messages or make regular phone calls with a local phone number through BambooSIM in South Korea.
Use of data‑only plans still allows access to VoIP applications such as WhatsApp, Telegram, and iMessage, which can be used for both voice and text communication over the data connection.

BambooSIM offers 46 single‑country data plans for South Korea, with no multi‑country plans available. The available plans span a price range from $2.25 to $131.95 and provide data caps between 1 GB and unlimited. Some plans give a fixed data amount for the validity period, while others cap the data allowance on a daily basis. This range gives travelers flexible options for short stays up to three months.
