Dual SIM
is a Term used for Phones that has two SIM sockets and allow the phone to work with both SIMs so a single phone will have two phone numbers.
Single Standby
is a Term used for Phones that supports multiple SIM sockets and allow the phone to work with one SIM at a time and user can select which SIM to be active and switch to the selected SIM so making and answering calls can be done for the active SIM.
Dual Standby
is a Term used for Phones that supports multiple SIM sockets and allow the phone to work with both SIMs at the same time. Both SIMs are active to receive and make calls. No need to manually switch between SIMS. But you can only make and receive call from one SIM at a time. For example, when there is a incoming call for one of the SIMs and you pick up the call, you will not be able to make or receive calls for the second SIM until the call activities are stopped for the first SIM. In other words, call making and answering is not duplex.
Dual Receiving
is a Term used for Phones that supports multiple SIM sockets and allow the phone to work with both SIMs at the same time. Both SIMs are active to receive and make calls. No need to manually switch between SIMS. You can only make and receive call from both SIM at the same time. For example, when there is a incoming call for one of the SIMs and you pick up the call, you will be able to make or receive calls for the second SIM. Call receiving and answering is fully duplex.
