Did you just change carriers by any chance? If you did and you get that error then your iPhone may be locked to the carrier that it previously worked with. Give the previous carrier a call and ask them about getting your iPhone unlocked.

If you did not just change carriers and are getting that error then shut down your iPhone and start it back up again. If that does not resolve the issue then call your current carrier and ask them about error and the resolution.
