Nano Sim Card Question

Hi,

I have contacts stored on my iPhone 5 (which I got through my gmail account) and would like to manually transfer these contacts to the nano sim card.

Is this possible and what steps do I need to take to accomplish this? The reason I am asking if this is possible is that I am a first-time iPhone user and also not familiar with the nano sim card.

Thanks in advance for any help you can give me with this issue!
