Mobile phone hacking in Africa

Interesting piece on AfriGadget about mobile phone hacking in rural Africa:

One of the more interesting innovations is the development of a dual SIM card hack so that users can access multiple carriers.

This product has two SIM card slots in a single phone – primarily to support price sensitive/prudent consumers who wish to optimise their call costs by maintaining SIM cards from two different phone operators. As in many countries – calls to a customer using a different Ghanaian operator cost slightly more than those on the same network.
