In other words it allows you to use two SIM cards at same time or you can use one SIM card with microSD card.
One geek wrote a tutorial how you can extend functionality of yours Galaxy S7 by adding possibility of using two SIM cards and microSD card at the same time. Anyway I will show you how you can do that but you need to know that you are doing that at your own risk and you also need to know that there is possibility that guarantee will not cover this hack.
To enable dual-sim support simultaneously with microSD card for the start you will need to have cigarette lighter, scissors and patience. After that first thing you need to do is heat up nanoSIM with cigarette lighter, heat about 1 minute and after that you need to remove nanoSIM chip. The second step is to put this chip in microSD card so that it can fit together in SIM tray.
In the last step you need to insert microSD card on which is affixed nanoSIM chip which you have removed in first step, and if you have done all correctly then your Galaxy S7 or S7 edge should have dual-sim functionality with microSD card.
I just want one more time say that this procedure you do at your own risk.
