About Australia’s cell phone operators

Australia’s operators offer amazing technology, competitive prices and sell prepaid credit, allowing users to take advantage of cheap offers and deals. All networks offer customers 3G and 4G/LTE. 2G will be discontinued across the entire country in October 2017, so make sure your phone is 3G or 4G compatible. Aussies call their SIM cards SIMs and there are no real rules and regulations when buying them. Just make sure you show your passport and register your SIM card online once you have purchased it, with the address of where you’re staying. It would be easier to ask the store assistant to do this for you to save time. SIM cards and credit can be purchased from supermarkets, stores, kiosks and the main airports in Sydney, Melbourne, Canberra, Brisbane and Perth.

  • Australians speak English and love tourists, so you shouldn’t have any problems. Their accent can sometimes be a little hard to understand, but once you become accustomed to it then you won’t give it a second thought.
  • Ask the store assistant to set up the SIM card for you. If not, follow the instructions we have highlighted above or go to the official operator website to seek advice.
  • The majority of stores close at 5:00pm, with Thursday night being dubbed as “late night shopping night” as stores close at around 9:00pm.

TripAdvisor tips for the best SIM cards and where to buy them

TripAdvisor has many user comments that can help guide you through what SIM cards have been tried and tested in Australia.

Here are some top tips from TripAdvisor users:

  • “Any of the majors are good: Telstra, Vodafone, Optus. Telstra has more coverage nationwide, but if you’re sticking in Melbourne you won’t have any trouble.”
  • “SIM cards can be bought for around AUD$2 but they do not include any credit. If you are looking for a simple, non-cap plan you could check out the Optus plan which is only 10c per 30 seconds for calls and 10c per SMS. It is good for basic use.”
  • ”Buy a SIM at the airport or at any convenience store in Melbourne and have the staff assist you to set it up and put credit on it. You’ll need ID to get a SIM, so have your passport ready when you buy it.”
  • “You can pick SIMs up in department stores, electronics stores, and of course the phone company outlets as well.”
