Coverage differences across Australia

Australia is very large, and coverage varies significantly between cities and rural areas.

Important:

  • Cities → strong coverage
  • Highways → moderate coverage
  • Remote areas → limited signal

Even local SIM cards can lose signal in remote regions.

eSIM installed but not activated yet

  • If you installed your eSIM before departure, it may only activate once it connects to a supported Australian network.

Wrong SIM selected for data

Your phone might still be using your primary SIM.

  • Check: Settings → Mobile Data → Data Line → select eSIM
