I believe you've only had the car a short time? I don't know much about the ICE and less about the "InControl" system on the XE but the fact you have put a sim in a slot concerns me if you just need the nav system. The car has it's own telematics system and connects to DAB and GPS as well as the usual FM broadcasts. AFAIK I have no additional sim in my car but if yours had one before it may still be registered with the previous keeper. Your Jag dealer or Jag Cust Service should be able to update this. HTH - good luck!
