Hello, I don't use the phone function often. Perhaps on average I make/receive no more than three calls/month. I wonder if I should just go back to a large screen tablet which is much better for my eyes. The problem is Apple does not want to make iPad with phone function what does not require connection to the internet. Consider the case that I have no internet connection but somebody is calling me urgently. My Note Pro 12.2 is till very good and I can use it as a phone. The problem is that it is difficult to fully backup the phone without breaking the OS. It has happened twice that the annotated pdf files, website bookmarks and photos were all gone because the device failed.
