I never understood why Teslas with 4G LTE modems and pre-V11 UI firmwares won't continue to work, unless Tesla knows something top secret about the AT&T Enterprise cellular network.
The more I think about it, and am repeating myself now, I think the warning about 'may' not work was to get folks who didn't want to go to V11 to feel like they had no choice and force them to update
Perhaps you are right, hopefully not - though when/if that does happen, my phone-as-key-as-hotspot will take over connectivity duties.
Do you have an unlimited data plan? Using your phone as a hotspot every time you drive could be expensive.
I thought of that but then I realized it is almost exactly what I've always done BT (before Tesla) on road trips before, though with the added benefit of Apple CarPlay w/Waze and proper hands-free group text etc
From what I've read it wasn't that some suit in Dallas flipped a switch that shut down the whole ATT 3G network everywhere simultaneously. ATT shut down 3G so that it could use the allocation for LTE and 5G. So they probably are gradually doing the conversion. It was probably easier to set a fixed deadline so no one could claim to be shocked when their flip phone became a paperweight.
