MNRF – Mobile Station Not Reachable Flag

This flag is found at the HLR (Home Location Register) on either a GSM or UMTS mobile network. The flag indicates that a mobile is not reachable and thus prevents any further and unnecessary signalling. For example, the flag would be set in the event that a mobile station failed to respond to a paging message.
