Question about SIM cards in tablets.

I have an AT&T tablet. I'm using it without a Simm card and it seems to work well. It has a slot for the card. Will my tablet act any better with a Simm card? What is the purpose of the card? Thank you.
You need to use a sim card in order to utilize 3G/4G data. You would pay for a plan of some sort but have the ability to be connected to the internet not just on wifi.
