Yes, it is possible. The device on my third line was lost without insurance, so I swapped a SIM card into a AT&T prepaid device as a temporary replacement.

I assume you've already put the SIM card in...

It is definetly possible. It just depends if your phone is compatible with the network. Google your phones specs and compare them with AT&T's supported frequences. I would check with your local AT&T store if you are unsure.
