I used the Verizon app. Went to devices, upgrade device. The phones don't show up under Apple devices so I went to the chat when you hit the magnifier and + icon at top right. Type in whatever device. "iPhone 7 plus". The automated chat shows you a link. Go to it and you see the device and go through the whole process. Did it on my i6Plus
Personal thank you to you! I got my order in at 2:43AM ET! I did not do that silly trade in deal though. I prefer 2-year pricing:
Apple® iPhone® 7 Plus 128GB in Black
