Prepaid SIM cards (Physical and eSIM)
For most tourists, using a local prepaid SIM or eSIM is the most reliable and cost-effective option for mobile internet access in Perth. The three main mobile network providers in Australia are Telstra, Optus, and Vodafone (TPG). They all have stores at the Perth Airport (OOL) and in major shopping centers.
Telstra offers the best overall coverage, particularly for those planning to visit rural areas beyond city limits. However, it is often the most expensive. You can also use a Telstra reseller, such as Boost Mobile, which offers access to the full Telstra network at a lower cost.
Optus: Provides a good balance of coverage and price, with strong performance in urban and suburban areas. It offers specific "Flex Plus Traveller" eSIM plans. Resellers like Amaysim also use the Optus network and are known for competitive pricing.
Vodafone (TPG): The most budget-friendly of the three, with reliable service in urban areas. Resellers like Felix Mobile offer competitive deals on the Vodafone network.
