Unlocked Samsung Galaxy S3 my AT&T Sim is not recognized

I purchased and unlocked a Galaxy S3. I sim unlocked it, but it doesn't recognize my AT&T sim. The sim I have works fine in my Lumia 900 though. Anyone have any suggestions?

Thanks

its positively not locked before I unlocked I entered the code to display lock status, after I entered the code did the same and it said lock off. I got lock success after entering code. Not my first time unlocking a phone just for information

Yeah it sounds strange that it wont work with ur sim card and ok in ur Nokia
Btw Have you got access to another sim card on another carrier to check
In the phone? Prepaid card?
