Nokia Lumia 520 sim card

[WPCentral Question]

I purchased the Nokia Lumia 520 from Wal-Mart online and it came with a Go-phone sim card.
I need a sim card for straight talk in order to use straight talk services right?
Which straight talk sim card will work? Anything that is AT&T compatible?

You need a straight talk SIM of course!
Get the AT&T version of the SIM. (there are two out there, one for T-Mo phones, one for AT&T)

you will likely have to get some settings tweaked (APN settings, usually under access point in the settings) before data and MMS work properly though, but that's normal for the most part.
