All of this “connectivity” has seemed underdone and flaky ever since it was introduced. If it’s also, now, impossible to upgrade to 4G/5G, it makes the whole exercise a totally over promised waste of effort. I can’t see Tesla goofing like this. Makes VW’s ID3 software issues understandable.
It was very flakey on the Mk7.5. Very poor indeed.
(After this week's frustrations with my new Mk8, its not *much* better even after a total redesign)
The problem in this thread however is simply to do with the timings of when they released the Mk7.5.... 4G wasn't really a thing and 5G was a theory paper still under discussion. They had to do something.... in particular with the eCall thing, which needed to work anywhere in the EU, hence 2G/3G.
The ID3/Golf Mk8 uses 2g/3g/4g.
More of an imediate problem beyond cars though is that things like smartmeters use 2g/3g.... those need swapping out. As do other industrial control systems that are across all sorts of things for remote control/monitoring.
I think what's really poor though is that VW are basically giving up on providing digital services for Mk7.5 owners (the later ones with the eCall/esim) and not talking about providing an upgraded module - even if it costs money to replace.
