iPhone 14 and Apple One Family

[dgross1958]

I know I receive Apple One Family free do to my purchase of the iPhone 14 Pro Max.

I went in online and selected the free item and I keep getting a text telling me to make sure I update my IOS to the latest version.  This was the first thing I did when I got the phone.

The only other thing I can see is that I need to link my Apple account.

Can someone tell me how to do this (I was a Android user before)?

Thanks Much,

Doug
