I know this may be the dumbest post ever, but I have never owned or had a need for a cellular phone, so I have absolutely no idea how any of the Cellular Plans work or what they really do (to me they just look like a giant money suck). I have been making a living as a graphic/web designer/photographer exclusively on Macs for over 25 years, but I have never owned or used a "mobile" device - never even picked one up! I doubt that I would be making many phone calls from an iPad? I know for sure I will never send a "text" in my lifetime (I am holding out for them to re-introduce Morse Code as the next leap "forward"!). So I have two questions in deciding whether I should order a new iPad Pro with the "Cellular" add-on... (1) Based on the above paragraph, is there any advantage "for me" to have Cellular connectivity (over just WiFi)? I do shoot studio photography sessions both tethered to my Macbook Pro and I also have a CamRanger for WiFi connectivity between the camera and my MacBook Pro (which should also work with the iPad Pro via WiFi). (2) How much would it cost to add Cellular Service to one of these iPads. Apparently they are not tied to a Carrier Plan of some sort like the iPhones (as far as I can tell).
