I went to install my micro sd card a notice what appears like a sim card under where the micro sd card goes. what is that and how does it benefit the phone?
Who is your carrier? On the Note the the SIM card and micro sd card are stacked on top of each other with the SIM card on the bottom. So that's what you are seeing.

I am on sprint and as far as i know sprint doesn't use sim cards. Or does it? Can it have something to do with sprints upcoming sparks network?
Even thought Sprint uses CDMA, LTE is *technically* a GSM technology. The SIM card is for your LTE connection. Any CDMA phone with LTE will have a SIM card for the LTE connection.
