My boyfriend is addicted yo to porn and likes to visit adult friend finder sites. He has been caught by phone, computer, tablet, etc.
I believe he has a secret cell phone now, How can I find out if this is the case or not?

He's addicted to porn
You don't trust him to the point you have to look a maybe secret phone up
SOLUTION: Dump him
I think the only way to do that is on a pay site and you probably have to have the number to see who owns it. I don't think it works the other way around for cells.
