Swapping iPhone 5 SIM to Lumia 920.

So I got a Lumia for dirt cheap and I want to try it out as a daily for a bit just to get the experience of WP8. Does anybody know if I can easily swap the SIM back and forth with no problem? I understand that the iPhone 5 uses nanoSIM whereas the Lumia 920 uses microSIm. I got an adapter off of amazon for that.

What I'm worried about is whether the data and cellular service will work properly if i switch back and forth between them whenever I want.
