Does it work nowadays?
How was coverage in the US with the C2? What region?
I only tested the C2 in my hotel room, 4G (because my plan doesn’t allow 5G). Little Italy, San Diego, CA. The 10 IV was my daily in San Diego, and I even drove a bit around with a car to the north and such, up to Dana Point.
Well US Mobile wanted me to update my plan anyway so I had them send me a darkstar sim. In a Librem 5 it gets volte registered ok and works as well as a Librem 5 can…
But not as much luck in the xperia 10 II. Data is fine and sms works but the volte selector in sfos cellular network page just blinks forever. Never denied, just blinking. To sanity check I tried a voice call and got the familiar tri-tone no service sound. I had been using t-mo and the us mobile t-mo sims before, and I’d made the modem config changes you’d divined back in '22.
Did you need to do any modem config sorcery to get att and darkstar to work on xoeria 10 ii?
I’d be really stoked to use attt network on the xperia, which unlike t-mo is available in my basement!
