Answer 1

if you are using the same company  

Answer 2

First, check if AT&T has 1900 MHz coverage in your area. If you have it, then you can get the Prada or you can get a Quadband Phone.

Answer 3

You can, but you will not have any service in areas of the AT&T network that operate on the GSM 850 band, which is a lot of it.

AT&T operates on 850 and 1900 Mhz.

So, not a good idea to blow your $$ on that phone.
