How can I block my SIM card and phone?

Has your phone been lost or stolen? You can request a new SIM card and block the old one via your My Viking account. You can also block your device. To do so, you need its IMEI-number which you can find on your invoice or its packaging. 

The IMEI number is a unique code for your device, composed of 15 digits. Are you using Dual SIM? Then you have two IMEI numbers: one for each SIM slot. With eSIM, the IMEI number works the same way as with a physical SIM card.
