How do I access the internet on my PS3? Can I do it through 3 Mobile Broadband dongle? - 3 dongle tips

I am connected to my laptop via 3 mobile broadband internet dongle in my USB port connector and takes the signal or something.
I have a PS3 for Christmas and plugged the adapter into the USB port on the front of the PS3 and the green light on the dongle and it has been found, but in reality I can with this online and if so, how? That's what I'm cold.
I have no telephone at home (well, not a job anyway.)

Or if not can someone give me some advice (in simple terms!)
