A new and different question, but rather than starting a new thread, I believe it can best be served through this thread:
A propos the frustrating delays for the Wickenburg, AZ SpC, does anyone know if there is any need at SpC sites for ATT 4G service? It would seem to me that some sort of communications is necessary at all times between each Supercahrger and Tesla HQ (at the very least, think of all the data at the Hawthorne map).
And I know, most unfortunately, that there is no 4G (or LTE) ATT service at that site. Nor any 3G, nor Edge, nor any ATT at all.
There is good ATT service to the south - in Morristown. To the west - in the boondocks on the way to Tonopah. To the north, in Wikieup. But Wickenburg is one big, black, ATT hole.
Postulating is one thing. Knowing precisely that each of the 94 (94+) US SpCs do or do not have such service could be more productive.
