Telephones in Australia
Australian mobile phones rely on 2nd Generation (2G) technology and 3rd Generation (3G) technology, also referred to as CDMA (Code Division Multiple Access) and WCDMA (Wideband Code Division Multiple Access).
Australian mobile phones use the GSM (Global System for Mobile communications) European standard, and take a SIM card (Subscriber Identity Module).
You may use your phone with your service provider in your home country if you set up international roaming however this can be very expensive, and you might be better buying a new SIM card or phone when you arrive.
Some phones are pre-paid, which means you purchase credit to put on the phone before use, and some phones are locked on a contract, usually for up to 2 years.
