A4B9, do you have a SIM card installed in the SIM card slot? I don't. I spoke to the my Audi support team today. I feel like all the teams I speak to are getting given false information by the 'technical support team' which is that this won't be available in the UK until later this year and that we have to have the emergency SOS calling option which can't be retrofitted. Clearly neither of these are true. Discussing the subject with the My Audi rep, the emergency calling feature is dependent on having a secondary SIM card installed as the embedded SIM card is only active when the ignition is on (hence cannot unlock the car when it is off). So I think it's going to have to be a bit trial and error and the next step is to buy a SIM and give it a go. Not sure if inserting my iPhone SIM into the car would do the trick temporarily... Going to otherwise get one of those £30 for 12GB SIMs from Three which is valid for 12 months
