I just upgraded from a 5 to an iphone 6s. I ordered the phone through apple.com. I didnt trade in my old phone. I still keep gettimg calls on both phones. How is this possible?
Calls can also go to an iPad and a computer, and any other Apple device with facetime calling and your Apple ID signed in, Even if the device is wifi only or you remove the SIM card.
IF you want to prevent this, turn off FaceTime calling on the old phone.
