What would happen if you took the sim card out of an iphone 5?

If you take your sim card out of your iphone 5, would your iphone not work at all? Or would you still be able to play games and use apps on it?

I'm not good at english but if you are asking how to do so then you can follow this guide here

on how to insert sim card into iphone 5

if you take it out you won't be able to make calls thats it but i think you can still play games and stuff
