Yes, SIM cards work in Samsung cellphones, provided that the phone is unlocked and compatible with the specific network technology (GSM or CDMA) used by the SIM card. Most Samsung smartphones are designed to accept SIM cards from various carriers. Simply insert the SIM card into the designated slot, and the phone should recognize it, allowing you to access mobile data and make calls.
Yes, they most definitely do.
