Using my AT&T sim in an unlocked dual sim phone

I purchased an unlocked quad band dual sim phone in Asia and want to use my AT&T sim in it.  when i insert the sim in the phone, it does not read/recognize it.  How do I get the sim to work on the dual sim phone?  any tips or suggestions are greatly appreciated.

if just putting it in doesn't work I don't think anyone here can really help you, not even AT&T

Make sure your dual-phone SIM is capable of supporting 3G SIM cards. To the best of my knowledge not all of them do, or not in both SIM card slots. So if it doesn't work in either slot, chances are it's not compatible with the AT&T SIM.
