they track the id of the phone you have

various numbers you see when you take the battery off, and switch it off

I have a cheap one I use as an mp3 player. When you plug the sim in it says "invalid sim"

When I went to get my other phone fixed in the shop, the guy went to pc and put my "invalid sim" codes into his computer and went "yep, someones been naughty and reported that stolen, then sold it to you, it's a blacklisted phone"
