Quick and easy activation

You can activate eSIM quickly and easily. All you need is an eSIM-enabled device, an internet connection and a QR code, which we will send to you by e-mail.

Wide range of compatibility

Do you have a device that cannot be connected to the Internet directly (eg an eSIM watch)? Use a smartphone or tablet and connect to the watch via Bluetooth.

Order online

To get eSIM you will need an existing phone number in 4. If you do not have a 4ka SIM card, order it online or at 4ky points of sale.
