Can I Switch My Sim Card From My LG Xenon To My iPhone Generation?

[pabiox]

If I switch it will the phone automatically work? If I do that will I have to pay for the data plan? Because I don't want texting, or internet. I only want to call on the iPhone. Thanks

It'll probably work if it's an AT&T sim card BUT AT&T will probably force a data plan on you and really, if all you want to do is make phone calls, you probably don't want an iPhone. Almost anything has better reception.

AT&T will definitely know you have an iPhon and will add a data plan. No way to avoid it.
