Continuity phone calls on iPad without internet access
I am trying to setup an iPad as a radio replacement in my vehicle and want it to handle calls for me so I can go hands free. I have an iPad Air 2 wifi only and an iPhone XS. I can supply a WiFi router in the vehicle but it will not have internet access but will allow to iPhone and the iPad to communicate. Will this work? I don’t have the access point yet and don’t want to buy one if it will not work. Thanks!
