A Dual SIM Smartphone allows you to use two SIMs in one phone. This can be very useful for travellers who wish to use a local SIM in their destination, but also remain available on their usual home number.
This is possible because although both SIMs are available on standby at all times and calls or texts can be received by either SIM. Only one can be actively used at a time. In order to make a call or send a text, you need to specify the network to be used for that action. Either one SIM or the other can be chosen for data, which can be configured via the SIM management menus on Android and Windows phones.
