But how? I can't see any realistic chance of a broad international agreement. Remember that it works both ways, too. What would you do if your phone stopped working because a telecoms company in (say) Nigeria accidentally asserted that your IMEI was stolen? Saying "wouldn't it be great if the world could co-ordinate" is not the answer as it isn't realistic. It's avoiding the problem and the need to come up with practical solutions. Or even an honest "it can't be done" answer.

That makes sense - an earlier response to my comment about how apple handles things with user PINs is probably a better approach.

Surely carrier A wouldn't let carrier B be able to block an imei belonging to their customers. If carrier B did block it though, you, customer of carrier A, wouldn't be able to roam in the network of carrier B - but still work fine in your home network of carrier A. However, that results in carriers needing to assert ownership over an imei, which would be come quite a mess - so it very well could not be done. I do believe national blacklisting registers of imeis, as already done for many years in certain european countries is much better than not doing it though.
