How do I put another phone in my fmp?
iPhone X
Same way you did the first one.
If both devices share the same Apple id, then they will both show up on find my iPhone, when you sign into find my iPhone from that id.
If they are not, then you would have to sign n from the Apple id of that phone to see it on find my iPhone.
