I was debating an unlock req on the original announcement thread, so feel free to stitch this there if needs be.
SpaceX just launched the first 6 ready direct to cell T-Mobile enabled satellites a few moments ago along with more standard batch.
I presume as they are the roaming partner to One, and the angle of insertion that usually passes both NZ and the US, this is likely the milestone One needs to start their own testing soon after?
