All international roaming usage charges will be incurred on top of your existing allowance. Here are some tips to help reduce costs associated with using your phone overseas.
Manage your mobile data usage
Be aware of your data usage and where possible, you should turn off the following:
Automatic software updates or app updates
Location or GPS
Apps you don’t need
Your phone’s mobile data when not in use
You’ll still be able to connect to Wi-Fi, and you can always turn mobile data back on when you need to use it.
Good to know: Streaming and downloading content on apps and sites such as Netflix, Stan, Spotify, Apple Music, YouTube can use large amounts of mobile data in short periods of time. Before you leave, you should try and save content you want offline.
