An Inventive Calling Plan February 14, 2008

Posted by goodmind in Multiplication.

A SIM card “street hack” popular in Accra, Ghana demonstrates the power of Multiplication.  To reduce communication costs, many residents have adopted the practice of switching SIM cards, based on the operator of the person on the other end.  By combining two SIM cards into one, users can minimize cost, while maximizing convenience as the hack eliminates the need to reboot the phone after switching cards.  Talk about saving minutes.
Jan Chipchase of Future Blog also points out that

“in countries with a high proportion of pre-paid phones, a significant number of highly price sensitive consumers and an evolved mobile phone repair culture…enabling a regular phone to support multiple phone numbers on one phone. Imagine having AT&T + T-Mobile on one device.

In many parts of the world the mobile phone number functions as an increasing important form of identity, a single device may be shared amongst a family, friends or even village and the device is the enabler for activities ranging from banking and money transfers to capturing and sharing experiences.”

Not even Verizon’s family share plan can beat that.
