Start with the provider's map
Open the map for the exact plan you are considering. Boost's coverage page describes predicted outdoor coverage on the Telstra Pre-Paid Mobile Network. Belong's map concerns its own service on parts of the Telstra network. amaysim's coverage page covers its Optus-network service. These are different service footprints; do not substitute one map for another.
Check several real locations
- Search your home, workplace or campus, regular route and any regional destination you visit often.
- Check the applicable 4G and 5G layers, and whether your device supports them.
- Read the map's limitations. Boost says its predictions are for outdoor use and actual experience can change with buildings, terrain, network load and the handset.
- If reception is critical, ask the provider about the plan and test with an eligible SIM where possible before relying on it.
