The OP specified this isn't a discussion and his post was dated five days after he lost the device. That first post is a month old so he's probably moved on by now.
You could reproduce your post into a Tutorial on this subject. That would be valuable albeit not many posters read them if it's easier to start a new thread.
Point of interest though, here in the UK a SIM can;t simply transfer in the way you describe without applying for a PUK to pass to another carrier. I always answer posts such as these telling folks to contact the Service Provider asap to avoid getting a large bill for calls and mobile data the thief or finder is using. I reckon that should be paragraph one of any Tutorial and webworkings would probably provide some more essentials.
