Can I use my exisiting ATT plan+SIM with an Iphone?

[bikramkohli]

Hey everyone,
I have a Nokia E71x with an unlimited data plan on it. I was wondering if I got an Iphone, will I still be able to use my SIM with the new phone? Do I need to change my plan or anything? Will I encounter any problem if the Iphone is unlocked?

Basically, I want to ask that if I get an Iphone, will I need to change my plan or not?

Your advice is greatly appreciated.

Thanks,
Bikram

Depends on where you get the iPhone from, a store or a third party. What did your carrier say when you called them?
