Need some advice on buying my soon to be 14 year old daughter a B-day present- she wants an i-phone ( apparently no other smart phone will do) . If I purchase the phone - she will pay the monthly fees as neither I or my wife have a smart phone - so we currently have no data in the Verizon package. Question is= which one should I get her? Is there a huge difference in them? other than the Memory size? I don't use my phone for anything other than text and basic phone - I had a Zoom tablet , but I never used it - so cancelled the 4G data stuff. So I have no idea on the smart phone stuff.
