hi is it possible to use wifi to download a book onto my old iPhone no sim so I can then play it without any wifi connection like old books? For instance I have audible purchased books and I want to put two of them on my iPhone and I have 3 old iPhones, instead of taking up room on my current iPhone that does have a simm card? Hope I am making sense. I Have 5, 5SE and 6 iPhones.
