How to Use Your Phone Overseas Without Being Charged
If you’re travelling internationally, one of the first questions you’ll ask is:
“How do I use my phone overseas without roaming fees?”
For Australians, using a mobile phone overseas has traditionally meant expensive roaming, buying local SIM cards, or struggling with airport Wi-Fi. Thankfully, that’s no longer the case.
This guide explains the best and cheapest way to use your phone overseas, whether you’re travelling to New Zealand, Japan, Europe, or the US.
Will My Australian Phone Work Overseas?
Yes — most Australian phones work overseas, as long as they are:
- Unlocked
- Compatible with international networks
- Relatively modern (last 5–7 years)
Popular phones that work internationally include:
- iPhone XS and newer
- Samsung Galaxy S20 and newer
- Google Pixel 4 and newer
If you’ve ever wondered “will my phone work overseas?” the answer is almost always yes, especially if it supports eSIM technology.
