Sounds like your iPhone is carrier-locked and you are trying to use a SIM (not "SLM") from a different carrier.
You cannot remove a carrier lock, we cannot remove a carrier lock, and Apple cannot remove one, either. Only the carrier to whom the phone is locked can remove their lock – if they choose to do so. If you are not their customer, or if there is any money owed on a contract associated with the phone, the odds of them helping you may be slim.
