Dual SIM Cards: AT&T and T-Mobile On One Device
Jan Chipcase points us to a very useful “street hack” he discovered in Accra, Ghana. Consumers who want to optimize their call costs are combining two SIM cards into one, enabling a normal mobile phone to support multiple phone numbers. This would allow a phone to run two or more service providers at the same time.
According to Jan Chipcase:
The hack is a response to an existing behavior - the practice of carrying separate SIM cards in order to reduce communication costs. It typically costs more to call someone on a different operator than the same and before this hack these consumers were willing to put up with the hassle of turning off the phone, switching in a new SIM card, and waiting for the phone to reboot.
