Several countries are tracking cellphones to understand who may have been exposed to coronavirus-infected people.

South Africa is about to follow suit, explains tech journalist, BRYAN TURNER. From Israel to South Korea, governments and cell networks have been implementing measures to trace the cellphones of coronavirus-infected citizens, and who they’ve been around. The mechanisms countries have used have varied.

In Iran, citizens were encouraged to download an app that claimed to diagnose COVID-19 with a series of yes or no questions. The app also tracked real-time location with a very high level of accuracy, provided by the GPS sensor.

In South Africa, preparations have started to track cellphones based on cell tower connections. The choice of this method is understandable, as many South Africans may either feel an app is too intrusive to have installed, or may not have the data to install the app. This method also allows more cellphones, including basic feature phones, to be tracked.

This means that users can be tracked on a fairly anonymised basis, because these locations can be accurate to about 2 square kilometers.
