First question - is it cheaper to do ATT next with a 16 GB iPhone 6s plus (roughly 32/month) or just sign a new 2 year contract (which I believe is $40 a month)? Is this ATT next thing actually cheaper than just doing a two year contract? Also, after signing a new 2 year contract (I signed one for when the 6S came out), can I switch to ATT next in the middle of that contract? I would only do that if you guys say that ATT next is indeed cheaper so i will be able to upgrade every year. BTW - I am on a family plan. We have unlimited text/call, and we share 15GB of data each month with roll over.
