Right now, hundreds of thousands of people in the southern African country of Namibia are faced with a choice. At the end of next month, their phone service is going to be shut off permanently: to prevent that from happening, they’ll have to give up their data privacy. As a result, nearly two million Namibian citizens are facing a data privacy problem which may haunt them for years to come - and hundreds of thousands more are set to join them, or else they’ll lose their phone service for good. All of which raises the question: was making everybody register their SIM cards a good idea in the first place?
