International roaming is when you are able to use your mobile on another mobile network overseas while still being billed by your usual Australian mobile service provider.
This works because the overseas network provider has a commercial agreement with your Australian mobile network provider and will bill your home network provider for the calls you make while on their network.
Depending on your destination and the type of roaming available there, you will generally use your existing mobile number and mobile phone to make and receive calls, access voicemail and send and receive SMS.
Voice calls will usually attract a higher charge than at home and it may be easy for you to exceed you normal credit limit. Although voice calls will be more expensive while roaming, they will generally be less expensive alternatives than using data roaming services.
One of the features of a mobile is that you can usually (depending on your destination) take it overseas and use your provider's roaming services. However, international roaming services are premium services and it's very important to be aware of the roaming charges that will apply under your current plan and to consider purchasing a data roaming package if you are planning to use data services (the internet) on your smartphone or mobile device while you are overseas.
