If you plan to stay longer in a particular city, consider choosing our City eSIM Plans for added convenience.

You can purchase an eSIM at your convenience, either one day before your travel date or upon arrival at your destination.
Additionally, please note that to install the eSIM, your device must be connected to a Wi-Fi or a cellular data network.

You cannot make phone calls or use SMS with this eSIM plan.
eSIM Busan Plans are data-only and do not include a local mobile number.

We also offer a top-up service. You can find the “Make a Top-up” button in the email containing your QR code.

Please be aware that as this eSIM plan provides a Hong Kong IP address, you may encounter issues accessing services such as TikTok or other restricted services in Hong Kong.
