Visiting US with iPhone - have AT&T Card...

I have an unlocked iPhone 3GS. Off to US this weekend and told to buy a pay as you go sim which I have now received.

Not sure what I do next. Told to activate on AT&T website, requests IEMI etc however believe won't accept unlocked iPhones.

Any US citizen able to kindly advise??

Been to the USA pass 2 years and been using tmobile with no problems ....dont know about at&t.

I am using a pay as you go for years, first in my Nokia, since two years in my iPhone(s). Treat the simcard as any non supported and it will work. Insert in your unlocked iPhone once you touchdown in the US, will work then.
You'll have access to

once the simcard is working to manage your account for refil, book Net packages and so on. Works perfect.
