Nope, the 1520 uses the smaller Nano Sim Cards so you won't be able to use your 920's SIM. You can grab one (for free) at the AT&T store though, just bring in the 1520 and they'll give you a sim. With the release of the Smartcard App, if you're interested in using the mobile payments via NFC then you should ask for a Secure Element Sim (also free)
