Other than keeping your device turned off while overseas, the safest way to avoid roaming charges is to keep your phone in ‘flight mode’. Also known as ‘Aeroplane Mode’, this feature disables all mobile network connectivity to prevent calls, texts and any data usage from installed apps.
You can also enable WiFi Calling and connect to a free WiFi network (while still in flight mode). This will let you to make and receive calls and texts to New Zealand and Aussie numbers without incurring roaming charges.
Calls to any other destination (including the country you’re in) will be charged at our Standard Mobile Rates.
