Brazil Blocks Foreign Mobile Phones
First time accepted submitter fabrica64 writes "The Brazilian government has today started blocking mobile phones not sold in Brazil (Portuguese-language original), i.e. not having paid sales taxes here. The blocking is based on IMEI, and if you come to Brazil for the World Cup in June and think of buying a Brazilian SIM card to call locally at lower rates, then it won't work because your mobile's IMEI will be blacklisted as not sold in Brazil. This is not a joke, it's true!"
I do believe Turkey blocks on individual IMEI. At least that was what I was warned of before I went for a visit. It happens after a few weeks so tourists are probably fine. Reference: http://www.turkeytravelplanner...
