Why does my phone say 'Network Registration Failed'?

If your phone is showing 'Network Registration Failed' it can mean a few things:

1.  If you have just been connected and your old service providers SIM has stopped working, simply turn your phone off and on to fix this issue.

2. The handset may be locked to Telstra or Vodafone and you will need to get your phone unlocked by them for it to work on the Optus Network. You can confirm if your phone is locked to another network by putting your new Moose SIM in a phone that you know is not locked to Telstra or Vodafone. If your phone is locked to either Telstra or Vodafone you can follow the respective linkes below to start the unlocking procedure.
