http://forum.xda-developers.com – hey guys i got my GS3 about 3 months ago on ATT and im looking to get the NOTE 2 unlocked...i have my own plan on ATT and my family has a family plan on ATT but not using data/paying..im going to give my GS3 to them when i get the note 2.. do GS3 on ATT require data plans if i give it to them? i remember i gave my ATT iphone 3GS on my lil sis and i forgot that ATT will detect it and add a data plan..not sure if ATT will do the same if i give my GS3 to my family.. thanks (HowTos)
