Hi - can anyone advise / help please. Have a 4.0 Daimler Sovereign which has a static phone in the arm rest. I have tried to connect with a 4G Sim card but it is not recognizing it. Do I need to find a GSM SIM card or is there something else that I am not understanding? If so, does anyone know a source? All the websites that advertise GSM don't in fact end up providing them.
Any assistance would be gratefully received and appreciated.
Many thanks
John D
