Domestic mobile networks have bilateral agreements with international mobile networks to enable their customers to use those networks when they travel overseas to make and receive calls using their Australian SIM card.

Charges for calls you make

Charges for calls you make from overseas are charged at the rate of the overseas network operator you are using plus any surcharges. This also applies to SMSs made while roaming although not all international networks support roaming SMS.

We do not publish rates for international roaming on our website  since the rates fluctuate depending on which overseas network is used and the exchange rate vs the Australian dollar at the time.

Charges for calls you receive

Callers from Australia simply dial your mobile number as if you were in Australia. Callers from the country you are in (or any other country except Australia) must call as if they are making an international call to Australia.

When you receive a call from Australia the person calling you pays for a call to your mobile number as if it was in Australia (this is only fair as the caller may have no idea that you're overseas).

You pay for the call to be re-directed to the country you're in plus any applicable surcharges. In some countries you may also be charged by the overseas network to accept the incoming call.

No GST on roaming calls

Your mobile number stays the same so that you know you can be contacted. Charges are billed back to the account in Australian dollars.

SMS and voice messages are products compatible roaming facility.
PLEASE NOTE when Roaming internationally, the roaming service is also charged for calls received. These charges differ from country to country as it is dependent on the carrier who's network you are roaming on.It's a good idea to check with your account manager prior to departure to get an indication on these charges. Please be aware that these charges are not 'set in concrete' and can change at the discretion of the overseas carrier.

1 Dec 10:00 Optus SMS 04nn nnn-nnn 0.22

1 Dec 12:00 SMS from mobile 04nn nnn-nnn 0.25
