SIM not connecting to Volvo sensus
I have installed a data only smarty sim in a Volvo XC90 2018. I can connect to the resultant car hotspot via my phone so I have an Internet connection. However despite trying all the ‘resets’ of the car’s Sensus system I keep getting the ‘no Internet connection’ message on Spotify and apps. I understand this might mean I need to get my Sensus system brought up to date by Volvo so that it can recognise 4G - can anyone confirm if this is correct? I think I need 3.7?
