It is best to purchase a SIM card or Australian mobile number when you arrive in Australia, as using your home phone number will incur high costs. There are two types of mobile phone accounts you can choose from:
A prepaid service gives you flexibility because you control how much you spend and can stop using the service any time. Pre-paid SIM cards are sold in many shops and supermarkets, as well as by mobile phone providers. After an easy set-up process with the provider, you will have a working Australian mobile number which you can top up with credit as needed. You can usually top up your prepaid service online or at a range of retail outlets. Your mobile phone provider can provide details on how you can top up your service.
If you will be using your mobile a lot, and will be in Australia for a fixed period of time for study, a contract might work out cheaper for you. There are numerous mobile phone operators in Australia, and you can choose from a range of phone plans where you can get the handset with little (if any) up-front cost; you then pay a fixed price per month for a certain amount of calls, text messages and data.
Many internet providers in Australia are also mobile or fixed phone carriers, and they offer pre-paid or contract internet plans similar to the above. If you choose a contract service, you will receive a modem, and pay each month for a certain data allowance. Ask the providers you are considering for details of plans that might suit you.
