your phone was carrier locked. Where you bought the phone from?
If the message is "SIM network unlock PIN" or "SIM ME lock code NP" or "SIM not Supported" or on an iPhone's About->Carrier Lock showing "SIM locked"
You have to ask the carrier where you got the phone from for the carrier help unlocking it.
(Sorry, for this particular issue, PM support would not be able to help)
