Frequently Asked Questions

What is an eSIM and how does it work?

An eSIM is a digital SIM that allows you to activate a mobile plan without using a physical SIM card. Customers with only an international passport as a valid form of ID can purchase and download an Optus Flex Plus Traveller eSIM when arriving in Australia and after clearing customs with a valid visa, making it easier for international travellers to stay connected. You’ll need an eSIM compatible device with My Optus app in order to download your eSIM profile and use your service.

Which countries can I make Unlimited standard international calls to?

Your standard Optus Flex Plus Traveller plan includes unlimited standard international calls from Australia to the following countries:

Brazil, Brunei, Cambodia, Canada, mainland China, Colombia, Denmark, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Laos, Lebanon, Malaysia, Mexico, New Zealand, Norway, Poland, Romania, Singaopore, South Korea, Spain, Sweden, Taiwan, Thailand, Turkey, UK, USA and Vietnam.

Can I make international calls to other countries besides the ones listed?

Customers will need to purchase an add-on to make international calls to countries not included with a standard recharge.  Customers will have the ability to purchase the $5 International Talk Add-on which provides 300 minutes of standard international calls to 50 selected destinations, as well as the $5 Extras Credit add on, which provides $5 of credit that may be used to call international destinations at the rates advertised on the Optus website, see optus.com.au/prepaidint for details. T&Cs apply.

How does the speed work on each plan?
  • The $5, $20 and $35 plans provide access to network speed capped at 150Mbps (actual speeds will vary and may be slower).
  • The $45 plan provides access to uncapped speed for the duration of the plan.
What will speed caps mean for my experience while using the Optus network?

A speed cap of 150mbps is great for day-to-day usage of your mobile devices including video streaming, video calling, web browsing, social media, email and messaging. If you are downloading or transferring large files (such as movie or gaming files), it may take longer than it would at uncapped speeds. If your plan is speed capped, it’s important to note that the speed cap is the maximum speed you may get access to. Your actual network speed may be slower and will vary depending on various factors including your device, location and source of download.

Can I access the 5G network on Optus Flex Plus Traveller?

Yes, all Optus Flex Plus Traveller options provide access to the 4G and standard 5G Networks (non standalone) subject to speed caps on select plans. You’ll need a 5G compatible device to access 5G, which is only available in selected areas (excluding NT) – for coverage details see optus.com.au/coverage.

How does the recharge process work?

Optus Flex Plus Traveller plans do not offer auto-recharge. You will need to manually recharge your plan through the My Optus App, the 9999 SMS menu, or via our website at optus.com.au/recharge (vouchers cannot be redeemed on this plan). Each plan can be recharged with an option which best suits your usage, with options available like the Unlimited Data Day Add On for $6.

What is an Activation Bonus?

When activating a new service onto Optus Flex Plus Traveller plan with selected recharge denominations, you will get access to bonus data for your first three recharges. Data will revert to your standard inclusions after this period.

What are Add-ons, and how can I add them to my plan?

Add-ons are additional options you can add to your plan through a variety of methods (such as the My Optus App, optus.com.au/recharge, the 9999 SMS menu, or the 555 IVR) to enhance your experience. Options include:

  • Unlimited Data Day Add-on ($6) for unlimited data with uncapped speed for 24 hours 
  • International Talk Add-on ($5) for 300 minutes of standard international calls to 50 selected countries.
  • Extras Credit Add-on ($5) for international calls and messages from within Australia, roaming (excluding MMS) while overseas in selected destinations and selected premium SMS services for 14 days.
  • International Roaming 1 Day Add on ($5) for 1GB data, 50 standard international SMS and 25 mins standard international calls to use while roaming in 150+ Zone 1 countries.
  • International Roaming 14 Day Add on ($25) for 5GB data, 50 standard international SMS and 50 mins standard international calls to use while roaming in 150+ Zone 1 countries.
  • International Roaming 28 Day Add on ($45) for 10GB data, 100 standard international SMS and 100 mins standard international calls to use while roaming in 150+ Zone 1 countries.
  • International Roaming 6 Month Add on ($75) for 15GB data, 100 standard international SMS and 100 mins standard international calls to use while roaming in 150+ Zone 1 countries.

Fair Go Policy applies. Actual network speeds will vary. See below for full T&Cs.

Can I use my Optus Flex Plus Traveller plan after the specified days (e.g., 5, 14, or 28 days)?

The inclusions provided with Optus Flex Plus Traveller plans are valid for the duration specified (5 days, 14 days, or 28 days). After the expiration, you will continue to have access to in-bound only services for 186 days following expiry. You will need to recharge or select a new plan to continue using the service for outbound services (calls, SMS and data).

Is there customer support if I have issues with my plan?

Yes, Optus offers customer support for travellers through the website, app, or physical store locations for any issues related to SIM activation, recharge, or plan usage.

What happens if I decide to stay in Australia for a longer period?

You can decide to keep recharging the Optus Flex Plus Traveller SIM but if you are opted into marketing you may be sent alternative Prepaid plans to consider.

How long will it take to get connected after I land?

In most cases, activation of a service with a new number shouldn't take more than 15 minutes – but it can take up to 4 hours in some cases. 

For eSIMs, the activation process will commence once your eSIM order is placed and you'll need to download My Optus app to download your eSIM and use your service (access to WiFi required).  If you don't have Australian ID, you'll need to wait until you've passed through immigration to purchase your eSIM online.
