     Thanks for wording it so succintly! That's indeed the gist of the   
   issue.   
      
     An interesting experiment would be for you to do the following:   
      
     Switch off 'Mobile data' (you have found where that switch is on your   
   phone) *and* switch off Wi-Fi. Now see if you still can make or receive   
   a phone call or/and can send or receive a SMS message.   
      
     My 'guess' is that you can still do that. If so, we've proven that the   
   'Mobile data' part (read: Internet access) is off / no longer in use,   
   but the *other* data for calls and SMS is still on / in use. And that is   
   exactly my point.   
      
     FWIW, I can't imagine it's diffferent for you and for me. AFAIK, this   
   is world-wide technology and not location/provider/phone/etc. dependent.   
      
     BUT, of course I could be wrong. Happened before, so it's bound to   
   happen again. :-)
