Dual sim, dual standby... That's the official terminology for both sims being active at the same time.
When dialing a number, there are 2 buttons on the screen to initiate the call, one for each sim. Same when composing a text message.
One small thing to remember, only the sim in "Slot 1" is capable of 3g HSDPA+ data speeds... Sim 2 is limited to 2g data speeds, so you have to consider this when deciding which sim goes where. You can switch data between sims with a quick menu selector, so it's really very convenient.
