The story is and always has been: Send it in for repair.

If your screen is broken, you send it in for repair. If your speaker is broken (which happened to some, IIRC), you send it in for repair. If your USB-port is broken, you send it in for repair. Yet, if your SIM-card-holder is broken, all of a sudden it turns into a semi-esotheric mythical stuff and people want "answers" and "transparency" instead of having their phones fixed?

I'm not getting it. And again, maybe it would help if you could just make up a possible "answer" you'd have expected from Jolla so that we know what you actually talk about.
