I used the white SIM. The black one is still stuck to the card, never put it in any phone. I’ve never gotten the 10 II to register with T-Mobile or USMobile by just putting in the SIM. The first SIM I tried on the Sony first, nothing happened, tried on pinephone and it started working. Put it back in Sony and it registered OK for a few days then went to denied about 4 days later. At this point it didn’t work in either phone.
I got a replacement from T-Mo from a retail location, but that one did the same thing – I tried it in the Sony, got nowhere and then put it in the pinephone and it worked. I have not dared put it in Sony for fear of killing it, too.
Third attempt I got USMobile SIM and put it in Sony. It’s been in there a few days now and I’ve never gotten anywhere but Denied. I haven’t tried it in any other phone yet.
