Mobile operators in some countries like the USA and Australia, are either starting to or have already shutdown their 3G networks. From 28 October 2024, all 3G networks in Australia are due to shutdown. Without an up-to-date phone, you won't be able to use voice services while roaming.

Slingshot Mobile is powered by the 2degrees network. To avoid any issues when using your phone overseas, check the 2degrees list of VoLTE roaming capable devices before your trip.
