Question. Thinking about picking up a LTE Ipad of some variety, likely the Mini 4 form factor, mainly because of the GPS in there. Scenario: Assuming if I get a cheap data SIM card/plan, but often I'll want to have Imessages (and sure Facetime calls too, why not) from my Iphone come through there. I assume I have to turn LTE off (or of course not have a LTE Sim in) for that to then connect via Bluetooth and Wifi, to the Iphone. Fine. However, will the Ipad (or Icloud account?) have both numbers associated with the LTE tablet, that being the Iphone phone # I want connected to get Imessage, and, the # that is assigned to the data SIM card? Obviously I want to pick only one at a time but will I have that option? Or is the LTE Ipad (or account) only able to have one number associated with it while a Sim is in there, that being the number on the LTE Sim? Pretty sure I can do what I want, but someone please confirm how that is handled by the Ipad. TIA.
