What does "T-mobile Unlocked" Mean?
I am trying to buy a new iPhone 6 and I found an individual that is offering me one? He told me its the gold 64 gb version and that it is t-mobile unlocked? Can someone explain to me what it means by "T-Mobiled Unlocked"? Does it mean that the iPhone 6 is from T-mobile, but it has been unlocked to be used with an carrier with an insertion of the respective sim card (i.e if I insert a att sim card then the phone will work even though it came from t-mobile)?
Thanks for your help!
iPhone 6, iOS 8.1.2
