Hey wilburshere ,

To confirm, yes your unlock Galaxy SIII will work with AT&T in the states

I can confirm it will work with 2G speeds 100% but for 3G/4G you will need to check what network bands your phone uses and confirm that they are the same that AT&T uses.(sam with the iPad)

but 100% it will work for phone calls and data on 2G speeds just pop in the sim and you are ready to go.

Cheers,

James

2G Network GSM 850 / 900 / 1800 / 1900
