A:AnswerHi Marcia,
Since the phone you purchased is locked to AT&T's network only a SIM card from that carrier will work. You may contact your provider/carrier to see if they have a way to get this to work on their network or unlock this. It may be possible to unlock the device by rooting the device. Please be aware that rooting will typically void any warranty on the phone, but may be your only route to work with your carrier.
A:AnswerHow much you pay monthly would depend on what plan you go with and if the plan is just for you or if you have others on your plan as well. Will be more if you're the only one in the contract you benefit more with others if you're not wanting to pay about $130 alone for just one phone.
A:AnswerHi! Thanks for your question.
The phones biggest differences is size, the camera is the same.

A:AnswerHi! Thanks for your question.
This phone is only sold at Best Buy locked to the carrier, and there is no possible way to ever unlock it.Most phones sold in U.S.A. today are locked to a carrier. The same is for the phones we sell. I have provided a link to the unlocked phones we sell, a very large selection. If it has a carriers name in the title, it is locked to that carrier. If it has unlocked in the title, it is unlocked. These phones can be used on any GSM SIM card carrier, anywhere around the world.

A:AnswerThe S3 has a larger battery, larger screen with an HD resolution, more memory for multitasking, and the newest version of Android Ice Cream sandwich.
The S3 has a slew of new software tweaks, features and gestures which add to the user experience and make it superior to the S2 skyrocket.
