Do I need a new SIM for my 6?
My new 6 is prompting me via text from ATT about needing a new SIM to access all the features of my new phone. Why is this? Have they changed SIMs in some way? I thought they were all just nano cards.
iPhone 6, iOS 9.1
SIM cards do get updated, if you switched from your old phone you apparently need a new one from AT&T.
