Interesting way to lock up the stolen phone for sale on the street business. Hopefully that's all this achieves!
Not sure if this is related to same subject...
A phone I bought in Vancouver,left in October, last years model, and purchased in a London Drugs , was blocked after several months of use in Cuba. Apparently there were 12 phones with same IMEI #
Never got a good explanation.

Someone in Cuba got a hold of that phones IMEI, and used it to change the number on a bunch of stolen or lost phones. there would have been little reason to do that in Cuba. Now that trick doesn't work anymore.
