Why can't I find the permissions section of my application manager?

AC Question

I was trying to send a premium message to get information on an organization I am apart of. When I went to send it, it asked me whether I wanted to send the premium message, it asked me if I wanted to save a permanent preference so I said yes and I meant to press always allow but I accidently pressed never allow. I have been looking through my phone trying to find where I can change this and I cannot find anything.
