I provide the PAC and previous duly terminated their connection this morning.  A while later I was able to use the new ID sim and a couple of people  were able to phone me, so I though all was well.  However, my wife has been unable to get through and I do not know whether this applies to others.  Sim manager shows the iD sim but there are two lines below the Sim Name  - unknown and unknown number.  Why is my phone number not visible?
