Hey. I have a 64gb iPhone 6 that is subsidized by AT&T. Come September, my 2 year contract will be up. I'd like to stay with AT&T but will not be purchasing a new phone. Since my phone will no longer be subsidized(?), I'm not keen on paying the same monthly amount. How would I go about getting a 'no longer subsidized' rate? Or will my plan just automatically change? Also, how much can I expect to save per month? Thanks guys.
