Very helpful response! Many thanks.
Your wife is using her iPhone the same way I envision using mine. I wasn't aware of the iMessage possibility until you posted it, but if I'll have to log in to use it, it'll probably be a no-go, because my Apple password requires so many keyboard shifts that I've never managed to get through a log-in on my iPhone's tiny keyboard. On the other hand, I could text via email from AOL, for which I use an easier password.
According to How To Activate & Use An iPhone Without A SIM Card (Or Wi-Fi) - Macworld UK
, a SIM card is necessary, but only for Wi-Fi setup
, if the phone is locked to a particular cellular carrier; if the phone is unlocked, it can be set up with iTunes.
Thanks for the iPhone X suggestion, but it would be overkill in terms of both cost and capability.
The pics I've taken for eBay with my present 5 MP iPhone 4, and before that with a point and shoot that I believe was 3 MP, have been more than adequate for my needs, right down to detail, so the 8 MP camera in an iPhone 5 should more than suffice.
Don’t worry about 32 bit apps. There are none available on the App Store.
That's what I was referring to when I said ",,,32 bit apps - which aren't likely to be much of an option...," although I hadn't realized that they'd all
Also, the lack of 64 bit capability makes the "5" really
obsolete, and, therefore, considerably less costly than an "X" would be.
