This probably seems like a silly question, but gave an SE to a friend who's been using an old flip phone. He doesn't adjust to any new tech easily. Wondering if I can just go thru the set up without passcode, itunes/icloud pass, and without activating the phone number. I can set up the just wifi connection and he can play with it until he's comfortable enough with it, then later activate the phone number, add passcode, etc. Is that possible, or more trouble than it's worth?
