3rd-Gen iPad with 3-Ireland SIM (14.0).
Setup was a pain - the online purchasing system generates a pw that is *texted* to "the number"! So it was stuck in the SIM. Had to wait 24hrs for a new pw to be sent to my iPhone. Plus they ripped me off for €5- in the deal - "credit".
No "Personal Hotspot" field in Settings or Settings/General. No Network field in General.
Tech support has no input and just have an opinion about the "device" not offering "Personal Hotspot".
[@dchao99] Switching Off and On did not change this.
Moving on... and away from (3)Ireland!
