I entered my information into the website and uploaded the receipt. Next day I got an email that said the device wasn't clearly listed so I uploaded my EIP paperwork this time. Hope it works.
I entered mine the day I got the phone on March 4th. I have a second S7 Edge that got delivered Saturday but I haven't entered it yet. I wasn't going to but I think I will just to get the Netflix code. I don't care about the VR thing.
