For optimal 4G coverage, you are required to use hardware that is compatible with all Optus LTE network frequencies (including 700MHz). You must also ensure your mobile device supports 4G VoLTE to adhere with Mobile Handset Safety guidelines for making emergency calls to triple zero (000). Mobile Carriers may block non-compliant devices from connecting to the network at any time.

4G Network Information

  1. 4G coverage refers to the Optus 4G Plus Network (LTE 700/1800/2100/2300/2600 MHz). Access to the Optus 4G Plus Network is available when the end-user is in an Optus 4G coverage area with a network compatible device and SIM card connected to a 4G mobile plan. Outside 4G coverage areas, Optus 3G Network service may be available with a UMTS 900/2100 MHz compatible device. A number of factors may affect coverage including location, demand on the network and use of external antenna. When within a 4G coverage area, your call or data session may also access the 3G network. 
  2. Optus prepares coverage maps using the latest available data, tools and techniques to map Optus mobile coverage as accurately as possible. However as with any network based on radio technology, handset quality or local conditions may prevent or interfere with mobile reception within coverage areas, for example, inside concrete buildings, lift wells, basements, tunnels and road cuttings. High rise buildings may also suffer degradation of service. These maps are not an indication of in-building coverage. 
  3. Optus' coverage maps may show planned rollout, which is indicated on the map. These predictions are based on rollout schedules available at the time of publication and may be subject to change without notice as circumstances require.
