What does the plan include?

South Korea Data eSIM- Powered by CMLink(Instant Delivery) - What does the plan include?

This unlimited prepaid data eSIM provides a straightforward, one-time prepaid package with no auto-renewals. The data connection supports 4G LTE or 5G speeds depending on network availability, ensuring fast internet access for most activities, from streaming to navigation.

Daily data allowances get reset at midnight (UTC+8), after which you’ll continue browsing at a reduced speed of 128 kbps—adequate for messaging apps and basic browsing. For travelers who rely on maps or messaging, this limitation isn’t usually a problem, but streaming videos or large downloads will be off the table once the high-speed data is exhausted.

Since this is a data-only plan, you won’t get a phone number or be able to send SMS or make calls via your number. This makes it ideal for using apps like WhatsApp, WeChat, or Messenger for communication.

Coverage and network speeds

Expect connections at 4G LTE or 5G speeds depending on local network availability. Many travelers have noted that the connection is reliable, and speeds are sufficient for most online activities. However, keep in mind that coverage can vary depending on your exact location on Jeju Island.

Most reviews indicate that the setup works smoothly, with some users mentioning that the QR code was received quickly and set up took just a few moments. The support from the provider is by email, so it’s advisable to respond quickly if you encounter any issues.

How to prepare before purchasing

Before buying, double-check if your device supports eSIM technology. If it was purchased in China or Hong Kong, it might not support eSIM at all, so confirm with your device manufacturer or carrier. Since refunds are not available due to compatibility issues, doing this check beforehand can save frustration.

Also, ensure your travel plans are confirmed. The plan’s validity starts upon installation, so you don’t want to activate it and then realize you’re not on Jeju anymore.
