This sounds ideal to me! Let's think of some other possible pros, since the author hasn't seemed to bother:
Stolen phones can't be used.
No changing SIMs when you travel
No roaming fees!
One bill for cell usage and purchases
Apple's excellent customer support, full-stack
- to name a few. The main point is, the user doesn't have to mess around with installing a SIM card. In my opinion, the SIM is a holdover from a previous status quo, - we accept it because we've never known an alternative.
I believe it should be possible to virtually route the calls to whatever numbers you've decided - let's say you have one personal and one business number. However, you can switch of the business number when you leave the work, or limit incoming calls for personal number only to close family members, etc.
Besides, phone numbers are obsolete as well. I think this virtualisation should give possibility to move away from them.
