Question about Samsung Cell Phones
If you have ported the number assigned to this phone from Sprint to ATT, the phone is no longer usable with your number. New owner will have to call Sprint and get another assigned, which they can do over the air.

Open the back of your phone's cover. Take off the battery. The must be a small slot of small size. There may be a steel coverage, if present open and insert the sim. If what I told does not help, contact your phone dealer.

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:
