Do you think it's ok to check your husband's phone? Why or why not?

Trust is very important between a couple. If I want to look at my husband's phone, I would let him ask him first and not do it behind his back. And likewise I let him look at my phone. I see nothing wrong with looking at each other's phone since we talk about everything and I know who he hangs out with. I think if you start snooping, then that's wrong.
