Why won't the internet work on my nokia x6?

i got the Nokia X6 today and it is outright, i'm with optus and i've been trying to set up the internet on my phone, although it doesn't have any preloaded server internet points like it had on my old samsung. it had things like 'optus zoo' and 'optus internet' but now on this phone it isn't coming up with any of these options, do you know why? can you help? thanks
