Put a SIM from a different carrier in it. Or call Apple, give them the serial number, and ask.
There are web sites that claim to be able to tell you if a phone is unlocked by entering the IMEI. They lie; there is no way to know from the IMEI unless you are Apple. Don't use them.

Put a SIM from a different cell carrier in it and see if it works.
