Can anyone tell me some detailed information about Dual SIM phones.?

I have a new phone and has a clone.It Apple iPhone Dual SIM capabilities, but I'm not sure what are the functions of sim.Do I need to get another dual SIM card or is it fair to use the SIM card have one? There are no user manual included with the phone, just a guide "Quick Start" for so I am a bit in the dark. Thanks in advance @ Nicaboi is a sciphone … that's all I can say, I have it on ebay.

You may only use one card for that, but you can use both if desired, for different plans or accounts. It's pretty stupid, but sometimes offer ..
