Straight talk (cellphone)? Buying just the sim card?

mjoslin1990

I'm leaving Sprint (WAY too expensive), but I JUST got the new Galaxy SIII so I'm trying to find someone who will trade my sIII for their tmobile or ATT SIII. My question is to use it on straight talk do I need to get the phone unlocked too? or just if it works on one of those carriers its ok?

I have no idea thats why I'm asking It said any GSM phone will work. Help???

No the phone doesn't need to be unlocked. Straight Talk will send you a SIM that works with either AT&T or Tmobile's towers.
