wonder how many here would use a phone only with a data plan, without explicit voice. I actually did ... Got a SIM-free/contract free 6S Plus in Japan and put a MVNO sim in with 10GB/month and SMS for some 2500 JPY. I don't really need voice, I mainly use message and FaceTime and recently Apple Music. With voice I could easy pay 2-3x and for emergencies I still have a company phone. So I think a smart way of doing in my situation. Sure, sound like I could use an iPad, but our friends in Cupertino don't let us sync the watch with an iPad. Plus in the trains the size difference is quite significant. Anyone else ?
