We Connect/Car Net

Hello, I don’t look through all the apps and digital services at VW somehow. The search in the forum and on the VW homepage has unfortunately created more confusion than helped… So, if I understand this correctly, there is “Guide & Inform” and “Security & Service Plus” in my favourite equipment for three years. That’s the Car Net, isn’t it? And then I need the We Connect app and I could see if I’ve finished and the car to the No. But the T-Roc isn’t always online, right? Do I need the LTE stick for that? Or a second phone with a hotspot in the trunk? Do you know that from my test drives in Skoda Kamiq or Renault Clio, they’re always online – without anything extra, so they have a (E)SIM fixed… That’s not how the T-Roc is, is it? And Media Control is something else again, isn’t it? I can only use that in the car, or how?
