Telus blocks internet access via hotspot tablet sim

I need to use my tablet sim (data only plan) as a hotspot in my car - i cannot stop everytime to give passengers access to the hotspot on my Telus phone. With the tablet sim, my car has a permanent internet connection for remote access of functions, online radio, and apps. However Telus does not allow devices connected via that hotspot to connect to the internet - technically this is totally possible. Maybe Telus wants to protect their SmartHub product, but that of course doesn’t work with my car. Anyone else has this issue?
