CocoRoam eSIM Data Plans for South Korea

CocoRoam offers an unlimited data eSIM plan for South Korea called South Korea Unlimited 1d. The plan is priced at $3.50 USD and is valid for 1 day, with tethering allowed. Because the plan is marked as “unlimited, ” the data allowance is technically unlimited, but the description indicates that the speed may be throttled, meaning the normal speed may be capped.

Speed restrictions are usually applied under a fair‑usage policy, so after heavy usage the data will continue to be available but may slow down. If you need to confirm whether a fair‑usage policy is in effect or what amount of data remains at normal speed after throttling, it is best to contact CocoRoam directly before purchasing.

CocoRoam does not provide eSIM plans for South Korea that include a phone number or SMS capability. Only data‑only eSIM options are available.

Travelers can use voice and messaging apps such as WhatsApp, Telegram, or iMessage over the data connection to stay in contact, but the eSIM does not assign a local phone number or support traditional SMS.

CocoRoam offers 27 single‑country data plans and 47 multi‑country plans that include South Korea. The plans are priced between about $1 and $138 and provide data caps from 1 GB up to unlimited. Some of the offerings are fixed data‑cap packages, which give a set amount of data for the entire validity period, while other plans use a daily data‑cap structure that limits the amount of data you can use each day.
