My old iPhone 4 is no longer on contract and sitting in a drawer not being used. I would like to give it to my dad but he doesnt want to spend money on a data plan. He has great wifi service in his area which would be enough for him. Its a Verizon CDMA phone. Is there any provider that will allow phone service without requiring a data plan? He prefers to do prepay without a contract because he doesnt make many phone calls.
