Dual Standby is a Term used for Phones that supports multiple SIMM sockets and allow the phone to work with both SIMMs at the same time. Both SIMMs are active to receive and make calls. No need to manually switch between SIMMs. But you can only make and receive call from one SIMM at a time. For example, when there is a incoming call for one of the SIMMs and you pick up the call, you will not be able to make or receive calls for the second SIMM until the call activities are stopped for the first SIMM. In other words, call making and answering is not duplex.
