A:AnswerIf you have a current phone with At&T & your phone is eligible for an upgrade it won't. Otherwise, you'll have to pay, I believe, 30% of the price of the phone when activating if you don't have qualifying credit. It will tell you on the "fine print" what the exact percentage is.
A:AnswerWell, this phone is locked to the att network. It doesn't work with any other network unless you unlock it or (jailbreak it), but be careful one mistake and you'll have a very expensive paper weight.
A:AnswerNo, this is NOT a refurbished phone. BTW, NEVER purchase a "refurbished" phone because most offer awful warranties/guarantees. This is a BRAND NEW phone. I purchased the pink-gold one and love it. This phone is super fast and the camera on it is better than iPhone (my husband has an iPhone). I prefer Samsung because the quality is fantastic! IMO, I believe Samsung IS better than iPhone.
A:AnswerWhen you buy an "unactivated" phone, you are purchasing the hardware ONLY. You then manage your cellular plan, however you choose. Purchase a SIM card and minutes as you need them; take the phone to a carrier (AT&T, T-Mobile, Verizon, etc) and negotiate a plan with YOUR new device. You choose...but you do have the full upfront cost of the hardware and less negotiation with the carrier by doing so. Many European and Asian customers already do this on a regular basis. Its becoming a bit more common in the U.S. Good Luck!
