How can i access my pc from anywhere?

[DiamondxCrafting]

Hey. so as you know by the title, I want to know how I can access my pc from my phone from anywhere, if possible for free.
I have been using jumione which is ok but it doesn't work on 3g so I have to be on the same network, apparently there is a way for that but it doesn't, the app is very buggy and hasn't been updated for a while,does anyone know any good way of doing that?
-Thanks!

Tons of free options
First is Windows Remote Desktop. You have to be able to do port forwarding on your router for this.
Second would be Google Remote Desktop. You just need to have google chrome extension installed for this, no port forwarding necessary.
