    Just bought an unlocked galaxy s3 from ebay,at&t was the carrier and I got a sim card from straight talk then called them to switch my number from my old ST phone activate the sim.After a couple minutes they told me to restart it and try to call a number.Well I couldnt get through to any number I tried.One time my home phone rang but that was out of about 100 trys in a 24 hour period.I then took the sim card and put it in my old att phone and everything worked perfectly right away! Now is the s3 locked yet? Or is there a setting to make for it to accept the sim card.Im all confused. I did put in the apn setting like I was told but thats just for data,which I could only send a few texts out of 100 trys! Please help!! I love this phone,what can I try next

    ok people............i'm telling you, I think it is different for every phone!! I downloaded the straight talk apn settings app from play store, it is free!! And followed instructions, restarted..now i am getting pics!!! i wouldnt bother trying to type all these settings in that are here, there and everywhere,they are all different. i tryed a few, none worked. but, this took me maybe 5 mins. using an unlocked att phone, over to straight talk samsung galaxy s3 with sim, and i do think one of the comments about the app was it had to be phone with sim. But, i would try either way!! maybe they have updated it!!
