Thank you for contacting Customer Care. Both the Galaxy S3 and S4 use a micro sim card, so yes you can transfer from one to the other. If you have any further questions, please contact us.

Make sure that you not only get an S3, but it is by provider also.At&t; is a different configuratrion than verizion or someone else. The configuartion is a little different, enough so that it will not work. So really really look at it very close. Take your S 3 apart so that you can see the differences. That is what I did not do & what should have been easy cost me alot more. Hope this helped.

Worked fine for me on AT&T.; I just put the SIM card in from the old phone and I up and running in minutes.

Yes, AT&T; SIM card does work on this phone. This phone does not allow you to save your phone numbers on the SIM.

The rep from the at&t; store told me that as long as the phone is at&t; or unlocked the sim card is no problem. I brought the phone as a Christmas gift for my husband so I do not have conformation at this time.

If you are an ATT customer, which I am, then you just take your old Sim card out of your old phone and put it in this one. It should work. Any AT&T Go Phone should work. Only phones that are not ATT and do not take a SIM card wont work. Such as Verizon etc.

I live in the US and had the same problem. I have AT&Tand they told me it is because the phone is not assigned to a specific carrier. So there is no guarantee your data plan will work with an unlocked phone. They told me to call Samsung which got me no where. Samsung told me to call AT&T and they were able to fix it.

While I can't speak for everyone, the phone does work with my wife's AT&T.; We bought the phone, plugged the SIM card right in, and could immediately make calls. There were some more complicated settings necessary to make MMS work. Otherwise it was pretty straightforward.

If AT&T; is your provider, just insert you SIM card and all AT&T; network functions will immediately work as they should. You won't even have to visit the local AT&T; store for activation. The phones that are advertised as "compatible" or "unlocked" will not. They must specifically state that the phone is programmed for the AT&T; network as this one does. I bought two phones from this seller in the past year and both are still working fine and have been totally problem free. Even my elderly mother hasn't been able to mess her's up as she did with it's three predecessors (ha! ha!).

i have at&t and it works with mine, but it souldnt matter what service you have. it should work with anything that has a micro usb port; most especially, on samsung products.

I had the phone through Verizon and had no problem getting it activated. I am not sure about at&T.;

I am pretty much sure it will work with any variant of Galaxy S3. I have used it with my T-Moblie S4 and my wife's ATT S4 and had no problems. Just make sure to plug in the USB cable to a powered USB source.

Hi Tori,I used a T-mobile SIM card with the phone and it worked fine. I have a month to month plan on T-mobile. I think it will work on AT&T;, if you have a sim card because the phone is unlocked. Hope this helps :)

Does not work with my AT&T sim. Phone only seems to detect T-Mobile, but I have not tried with a T-Mobile sim

I believe you can. I used to have a basic cell phone from AT&T; with a go-phone plan. I took out my SIM card and installed it in the Galaxy phone with no problems. I first tested this by taking out my SIM card and placing it in a coworkers Galaxy phone from AT&T; and it worked. Just make sure this is an unlocked phone.

I am almost positive that you will be able to use that SIM card. I was told that any At&T; card can work in any At&T; phone. However, if the one phone is not 3g, then you will have some limitations. Since you are going from 3g to 3g, you should be ok. I was ok when I switched over to this phone. I had an intermediate phone that was AT&T; that was not 3g, i could not make international phone calls. So, I got this Pantech and am getting international phone call capability.

It works off the AT&T; network and my phone recognizes it as AT&T.; So it just might. You can get the sim card and just put a small amount of minutes ($10) on it as I did to see if it works. If it does you just add more minutes. If it doesn't then you're not out much money. If it works you will like the service. Hope this helps.
