Apple iPhone 6 Plus Unlocked GSM (S&D)

What is the storage space on these? I Didn’t see it listed unless I just missed it.

Third item in the listing:

Capacity 16GB

Anyone ever buy one of these S&D phones? Very beat up?

if purchased, can they be activated on a verizon plan?

I can only confirm that it will work on the carriers listed in the title.
