If you buy a full priced iphone 6s plus, will it have all your info preinstalled on the phone.. i.e. sim and data plan installed etc? what I mean is, if I buy a full priced phone, will my iphone 6 plus still works with the existing sim or apple will automatically transfer it? I remember when I got my iphone 6 plus last year, they automatically migrated my data on to the new phone. so I was driving with an iphone 5s already disconnected/no service.
