Hi yes you can use your AT&T sim in Motorola Atrix mobile only if it is unlocked one .Else if the phone is locked to some other network provider then until you unlock it from network lock .You can easily unlock your phone using sites like Classicunlocking.com here they are rendering unlock code for all mobile models at reliable cost .....After unlocking the phone you can freely use it with AT&T or any other GSM sim...
