I am getting the following error when trying to enable iMessaging or Facetime on my iPhone 13 Mini:
"This Phone Number Cannot Be Used by iMessage and FaceTime
You must have a SIM associated with an Apple Device for +44 xxxx xxxxxx to be used for iMessage and FaceTime"
I cannot find a way to associate my SIM with my iPhone either on iOS or BT.
I ported my number from my previous supplier using a PAC code 24 hours ago.
The SIM I am using was used in another device prior to my number being ported in.
