Mobile Number Portability

On-Net and Off-Net

The terms 'On-Net' and 'Off-Net' are used to describe call or messaging types. 'On-Net' is used when your call or message originates on your home operator's network and terminates to another mobile number that resides with your operator. It does not matter if the person you are calling is using the home network or is off Island roaming with a different provider. 'Off-Net' applies when the call or message is made on a different network, e.g. whilst you are roaming, or if you are using your home network and make a call or send a message to a number that resides with a different network provider.
