In order to encourage use of 000, mobile telephones imported commercially into Australia are required to be programmed to treat 000 in the same fashion as 112 (i.e. dialling with key lock enabled,use of any carrier,preferential routing,etc.) ]. On older or privately imported (e.g. roaming from another country) telephones,000 may not receive such preferential treatment.A proposed amendment to the Telecommunications (Consumer Protection and Service Standards) Act 1999 would prevent carriers from providing emergency services access to SIM-less devices,i.e. mobile telephones that do not have a SIM installed.
