[Ovmsdev] OVMS v3 First Board Layout

[Dominik Westner]

It is supposed to be rolled out across Europe over the next months. In US it already seems to be available. 
As this is a software only feature of the existing infrastructure it shouldn't take too long. But that information is only second hand. 
I'm mostly following what these guys are doing

I’m used to SIMCOM, but it seems their selection is getting complicated (particularly for 4G). I see the SIM5320A has 3G and GPS, which seems good but is quite dated now.
