So how does that sim work? I don't really understand
In June I'm going to London and Finland/Russia and I need a prepaid data sim, would it be best to just get my phone unlocked and buy somthing locally there?

my guess is seeing as all phones need to be able to make emergency (9-1-1) calls even if you are out of your area. the chip copies whatever info your phone sends when it makes emergency calls and keeps/tricks the phone in that emergency call unlocked state.
