NIS PC licence seems able to add other device and

.....I have had Norton send a email to my Android phone with a 'Set Up Now' button. But I am unclear how or if the PC subscription of NIS can also cover an installation on a phone. So that is as far as I got other than tapping the button which opens a sign in to register your purchase page. Tapping that promps me to sign into my Norton account, which works OK, but then asks for the Product key which I have here. But I am unclear if that will result in an installation to the phone or a trial, or another purchase.

 

Advice please.
