There are plenty of GSM phones available overseas; similarly there are many countries where someone can get an unregistered SIM. While for a hobbyist the cost of the resultant calls may not be worth it, for a multi-million dollar drug ring the cost will be noise. Ultimately it won't prevent those enterprises or terrorists from getting them.
