Connect to the WIFI of the Viking using the WIFI password inside the battery cover. Open an internet browser and type in the address 192.168.10.1 and use password carlsonsw unless you&#8217;ve chosen your own. Choose Networking, enable the modem choose the eSIM slot, and make sure that the modem is enabled. You can follow that link to activate the eSIM.</p>
