    Hi and welcome to Android Central.

    Which HTC phone do you have?

    If you're using a SIM from a different carrier than the one it was originally branded to is it unlocked?

    If the phone and SIM are from the same carrier, have you tried getting a new SIM from your carrier?

    Is your phone's SIM puk locked?
