Just checked and tray is NOT the same on 6 and 6 plus....
This is the 6 plus I just got in a trade. Does not sit flush on phone. Will not recognize SIM card on the 6 nor on the 6 plus.
Mine sits flush on my device (iPhone 6 Plus). Is it possible that the previous owner damaged the SIM card tray/tray mechanism?
So your using a SIM card tray from an iPhone 6 on your 6 plus?
No, and I misunderstood your post. Sorry 'bout that.
