International Roaming: Add, Remove, Rates & More

International roaming allows you to use your Optus mobile service whilst overseas in over 180 destinations. Check the world map to see if your Optus service will work at your destination. 

  • Prepaid roaming: You will need 'Real Money' / 'Credit' / 'Roaming data' / 'Extras Credit' / 'Travel Credit' to use Prepaid roaming overseas
  • Postpaid (billed) roaming: Roaming usage is not included in your plan and will be billed on top of your regular monthly bill. So things like accessing email, social media, mobile internet, messaging and calls will cost you extra.

How to check estimated usage

International roaming charges can take a while to come through as they pass through different mobile networks. For this reason, the usage shown will only be an estimate - your Optus bill will show the actual usage charges. 

When viewing data usage, the time of usage will be shown in Australian Eastern Standard Time (AEST), not the local time where the data was used.

There are two options to check an estimate of your roaming usage:

Note: To minimise roaming charges use Wi-Fi where possible.

International roaming usage alerts

Where available we'll send free messages to keep you informed of your roaming usage. You'll also get SMS alerts each time you exceed approx. $100 of roaming usage. Roaming usage alerts are estimates and may be delayed.

What do I need to know before travelling overseas?

Stay informed and in control

Roaming Charges
  • Get to know our simplified roaming rates and zones
  • Consider purchasing an Optus Travel Pack. In selected destinations they provide greater flexibility and control as well as better value when using your Mobile Phone, Tablet or Mobile Broadband overseas
  • Call diversions to an Australian number or a number in the local zone destination are excluded from your plan and Optus Travel Packs. They will be charged at the standard International call rates for that destination
  • Roaming charges can sometimes take a couple of months to appear on your Optus bill
  • You're responsible for all charges incurred while overseas, just like you are at home
Tips for Travellers
  • Use secure Wi-Fi to access the internet on your travels (where you can)
  • Take note of any roaming usage alerts that we send to you
  • Get the latest version of the My Optus app before you go and use it or My Account over Wi-Fi to keep a tab on your usage, balance and bills when overseas.
  • Secure your device with a PIN / strong password
  • Consider adding a third party authority to your Optus account(s), so they can make enquiries on your behalf
  • Change the phone numbers in your address book into international format
  • Network quality, coverage and capability varies greatly depending on your destination. E.g.. Some networks overseas don't have 3G/4G functionality. See what's available here
  • You should check your mobile device's compatibility with the overseas networks / mobile frequencies that you intend to use. Most modern devices can use multiple frequencies, but we recommend that you double check compatibility. Here's an example of some of the differences that can exist with network frequencies:
    • Optus use: 
      3G Network: 900  / 2100 MHz
      4G Network: 700 / 1800 / 2100 / 2300 / 2600 MHz
    • Some operators in the USA  (for example) use:
      850 / 1900 / 1700 MHz for 2G / 3G / 4G
