Need Suggestions to block PMO triggers on Smartphone

Start by deleting all your bookmarks for any sites that lead down that path. When you have to actually type out a website address it takes a few seconds more and it gives you time to check your actions and say, "Do I really want to give up on the progress I have made so far?". You already know what sites I mean, they are feeders that always seem to lead you into you know what.
It was one of the things that helps me.
Parental controls on the phone, again it slows you down.
Go to bed earlier, don't let that empty time and space open up in the evening that leads to you know what.
Only use your phone when other people are around, don't surf alone, that's when sharks eat people, when they are alone, at night, surfing.
Never take your phone in the bedroom, ever, plug it in the kitchen to charge after dinner and don't get it until you leave in the morning.
Fill your time with other activities. Personally, I went and got this mythical document from the olden times called a "library card". I use it all the time now to read BOOKS. Specifically books on self improvement, cooking, how to make bombs, history, anything like that. I stay away from fiction as I may end up getting triggered by some stupid passage. Best part is, it's free. Get some boring books and read them at bed time, you'll pass out before you get to the PMO stage.
I look at books this way. Imagine all the time I pissed away on Porn, lets say its between 250 and 1000 hours in a year. Imagine I spent that time learning things from books, could I have learned something valuable? Of course I could. Books are like software for your brain, porn is too, only its nasty virus ridden stuff that does your hardware no good and corrupts other software. Fill you brain with good things so there is no room for the bad.

 

If you're using wifi, try to use OpenDNS.
I use it, it helps me a lot.
Also, I installed DD-WRT in my router and blocked other sites. This helped as well.
Besides that, I intend to root my Android phone and block 3G/4G too.
Any help you need, send me a message.

 

Sell it

 

Turn off your modem every night.

Also get K9 app, its free. Or if you use Windows phone get SafeKiddo, but that one costs money.
