did you have your phone unlock by a phone carrier or by someone else?

The phone is locked to a carrier other than the one you are trying to use. Use a SIM from the correct carrier, contact the carrier the phone is locked to to find out what their unlocking policy is, or return the phone to the place you purchased it and buy one you can use.
