Dear iPhone aficionados, Longtime Apple fan with a question just out of my realm of knowledge. I haven't used any land or cell phone service provider for almost a decade, and I love it that way. (When needed, I've sometimes used a voice-to-e-mail service for incoming messages and SkypeOut for outgoing ones. I barely ever use either.) For that reason, I've always owned an iPod touch. The Apple Watch made me upgrade to my first iPhone ever: a used iPhone 5s. Since I wasn't planning to use a carrier, I went ahead with a Sprint phone, not thinking that choice would matter. I was pretty astounded to learn that I needed to acquire a previously-used Sprint SIM card to even reach the iOS home screen and use the device. Maybe that's obvious reality to you in the phone-based world, but to me it seemed baffling. Anyway. I'm considering the lovely iPhone SE, and clearly the SIM-free option suits my phone service-free lifestyle. If I upgrade, am I going to need to do something unexpected to even activate and operate iOS?
