Norbert or anyone possibly direct me to a website where there is a technical description on how these Open Spots operate? Since I'm paying for wifi service in my car and the Open Spot fails to connect to the internet I'd like to send T Mobile and Magenta Drive a description of my device and look for an explanation from them as to why it fails to operate the way it should. Somewhere along the way it gets filtered out when going through the car wifi and I'd like to try and get an explanation from them. The Magenta Drive (ESIM) service from T Mobile/BMW is a fairly new service and maybe by some fat chance this problem could be corrected. It's just funny that both the iPhone and car share the same phone number and account via esim, but the connection via phone works fine but the connection via car wifi cannot access the internet even though it shows connected.
