Well, the SIM-card did arrive before the weekend!
When I came home on Friday it was there, waiting for me. I did a little happy dance and went inside to continue what I was doing when Rickard asked me how I could possibly stay downstairs doing the dishes (or whatever) when I could go upstairs and start up my new phone.
So I left the dishes to him and did just that.
An hour later he realised I would probably not go to the store to get groceries after all so he packed up and went instead.
