What You Can Expect from the eSIM

This eSIM from LINK KOREA offers a straightforward way to access Korea’s top network provider, SK Telecom. Once you land, you’ll receive a QR code via email a day before your start date, which you scan to activate. The process is designed to be simple, but some travelers have reported it’s not always as intuitive as hoped, especially if your device isn’t fully compatible or if you’re unfamiliar with eSIM management.

Device Compatibility and Activation

First, ensure your phone supports eSIMs. You can check your device by dialing #06# and confirming “EID” appears. If not, this eSIM isn’t suitable for your device. The provider emphasizes that only overseas passport holders can use this, and Korean passport holders are excluded.

Once you get the QR code, activation takes place immediately once your device connects to SKT’s network. Remember, the plan’s validity is tied to hours, not days—so if you purchase a 3-day plan, it will activate upon first connection and expire exactly 3 days later.

Voice & SMS Features

While the base plan is for unlimited data, voice calls and texts only become available after online verification. You’ll receive a Korean phone number along with 1,320 KRW voice credits, which cover about 5 minutes of domestic calls. Many reviewers have found the voice service useful, but some have faced initial hurdles during activation, as one traveler noted, “It took me an hour to understand and install everything.”

Ease of Use and Troubleshooting

Most users find the QR code quick and easy to scan, with stable 4G LTE signals. However, some reviews mention challenges, especially if the eSIM isn’t activated correctly or if the device shows “QR code is invalid.” In such cases, users should check their eSIM settings under Settings > Cellular (or Connections) > SIM Manager on Android, or Settings > Cellular on iPhones. Customer support is accessible via email and WhatsApp, which can help if you encounter persistent issues.

• Keep the email with QR code handy until fully set up.
