Transfering GoPhone sim into a Nokia N80 - will it work?

I have a cingular/AT&T gophone sim card in my current nokia 6030 right now. If I buy an unlocked Nokia N80ie, and put my sim card into it, will the phone and all its features work correctly?

It's my understanding that sim cards are universal with gophones. My experience is that I had a cheap basic Motorola gophone and upgraded to a Nokia 2610 (not expensive but I can check email with this phone, unlike the Motorola), anyway my daughter told me that instead of getting a new number and buying more time (since I had existing time already on the Motorola) just to take the sim card out of the Motorola and put it in the Nokia. I did and it works like a charm, it kept my existing address book and the time I had left from the last time I bought minutes.
