Does sph-a580 have a sim card if so how do you remove it?

I believe that there is NO SIM card in your phone. See this site for specs:

Usually your lock code is the last 4 digits of your phone number

The code *#06# should bring up the IMEI in a phone.Thing is, this phone is called a CDMA phone and these types of phones don't have an IMEI number.

I might be wrong, but, as far as I know, the SPH-M500 is a CDMA phone, and, as such, it lacks a SIM card. To either confirm or deny my point, please, download its user guide from this location.

The SIM card is "built-in" on this particular model. Not removeable in other words.

That phone is a CDMA phone and does not use a SIM card. Sprint phones and Verizon phones are CDMA and do not use SIM cards. AT&T and T-Mobile use SIM cards, but are GSM phones, a whole different technology/signal. Nextel phones do have SIM cards, and some "World" phones at Verizon have SIM cards for traveling overseas where there is no CDMA, but your Samsung SPH-M220 has NO SIM card.
Just in case you want to check anyway, here is a link to the user's manual:
