On some devices, you can simply adjust this in the settings.

Is this not the case for you? Then use the call button to enter and dial the following code: (*)*04*[old PIN]*[new PIN]*[new PIN]# (*) 

A small tip: on some devices, you only need to use a single asterisk (*) at the beginning.

For example, it might look like this:  (*)*04*1111*1934*1934#(*)

Important! Don’t forget this code, as it won’t be updated in your My Viking account. Lost your PIN? Click here to reset it.
