> stolen phone to new phone does not work :)

I'm curious about that, has this been tested by someone who "steals" the phone, and tries to migrate before the actual phone owner even realizes?

haha I was actually thinking of the case where you don't have your phone any more and want your signal history, but that's another way to read it :)

you need to be able to unlock the phone and then you need the Signal PIN code for this.
