I'm considering buying an Audi data pack (using Cubic Telecomm) to enable use of apps such as Alexa in the car which require Audi data to be bought.
My phone connects to the Audi Wifi hotspot (and I need that connection because I use Android Auto).
At the moment, as I don't have any Audi data, my phone uses the cellular data from my mobile even though it is connected to the car's wifi hotspot.
If I buy Audi data, the phone will start using that, due to the wifi hotspot connection. How do I stop this from happening please as the Audi data is way more expensive than the cellular data.
I'm using a Samsung phone on the Android.
If anyone has found a way around it, please let me know.
