I was looking to set my son up with an economical cell phone plan. I was going to give him my old ATT iPhone 4s and set him up with a plan that gives him voice, text and data. I'm a little confused after comparing the the ATT postpaid (Mobile Share Value Plan) and prepaid (GoPhone) monthly plans. ATT offers a prepaid monthly plan that is $60 a month with unlimited talk and text plus 2GB of data. On the postpaid side, a similar plan would cost $80 (no contract and BYOP) or $95 (2-year agreement with a new subsidize phone). Plus the postpaid plans have additional taxes and fees.
Am I missing something here? Why would I want to pay $20 more for the postpaid plan over the prepaid plan? Is there a downside to prepaid I'm not seeing? I can see the advantage of shared data plans if you have a bunch of devices, but we are just looking for a cheap single-line plan for my son.
I'm hoping some of you cell phone gurus can lend some advice.
