How can I access Unlimited Weekend Data?

If you're a new or existing customer on the $39, $49 or $59 Flex Plus plan, you can access unlimited data every weekend. All new customers need to do is turn on AutoRecharge during SIM activation. Existing customers can turn on AutoRecharge in My Optus app to get access from the first eligible AutoRecharge. You can also access unlimited data weekends from your 2nd recharge on the $35 AutoRecharge only plan. If activation or AutoRecharge occur on the weekend, you won't get access to Unlimited Data until the next following weekend day. For compatible devices only. Offer available until withdrawn. Excludes Traveller plans. Fair Go Policy applies.

Can I buy an Unlimited Data Day during an Unlimited Data Weekend? Yes, you can still buy an Unlimited Data Day anytime. It's a great option for weekdays or if you're not eligible for unlimited weekend data (for example, because your plan is not eligible or because you don’t have AutoRecharge on). We don't recommend that you buy an Unlimited Data Day on the weekend if you're eligible for Unlimited Data weekends. There will be no benefit to you because you will already have access to unlimited data at uncapped speeds through our Unlimited Weekend Data offer. To learn more about Prepaid UDD and other add-ons, please see optus.com.au/prepaid/plans/add-ons.

Can I access an unlimited data weekend if my AutoRecharge is on a weekend? An eligible AutoRecharge must have been processed by 11.59pm on Friday (local time) to receive access to unlimited data for the weekend that follows. If your first eligible AutoRecharge is applied on the Saturday you will get unlimited data on the Sunday only. If your AutoRecharge happens on a Sunday, you will not get the unlimited data weekend until the following weekend.

If you keep an eligible AutoRecharge turned on, unlimited data will continuously be applied to your service on the weekend (12.01am Sat to 11.59pm Sun).

What is an eSIM and what are the benefits?

An eSIM is an embedded SIM, where you can download a digital eSIM from Optus and connect without a physical SIM card.

What are the advantages of eSIM? This technology is embedded directly into your device, offering several advantages.

Connect to Optus faster: Don't wait for fiddly, physical SIM cards to arrive. eSIM technology is already built into your compatible device, for quicker, simpler connection to our best mobile network ever.
Easier digital setup: With an eSIM you can activate our great value plans, easily through My Optus app, simply by downloading your digital eSIM. Make changes or add another service with less wait time. You'll need an internet connection (via WiFi or hotspot from another device) to download the app.
Two numbers. One phone: Enjoy the flexibility of having two numbers on the same phone – one for work and one for personal use – simply by using both an eSIM and a physical SIM*.
More environmentally friendly: Because there's less reliance on plastic SIM cards, there's also less manufacturing and less packaging. That all means a lower impact on the environment.

*In some 5G capable phones, you won’t be able to access the Optus 5G network if you have an eSIMand a physical SIM active at the same time. Find more information and a list of affected phones here.

How can I buy a prepaid eSIM?

Buying a prepaid eSIM is simple with these steps:

Check Device Compatibility: Before purchasing, ensure your device supports eSIM technology. You can check this by selecting your device brand in the appropriate dropdown menu on our website or app.
Install the App: Download the My Optus App from the App Store or Google Play. Note that eSIM purchases can only be made through this app. You'll need an internet connection (via WiFi or hotspot from another device) to download the app
Purchase eSIM: Once the app is installed, return to the eSIM section on web and click on "Buy eSIM Prepaid" to proceed with your purchase. This will open up in your My Optus App.

Can I use a SIM plan on any mobile device?

We're switching off our 3G network from 28 October 2024, which means 3G services will no longer be available on the Optus network. Regardless of the SIM plan you have purchased, if your device relies on 3G for voice or data use, your service will be impacted from this date. This includes the inability to:

Make calls
Send or receive messages
Make emergency calls to Triple Zero (000)
Use data or connect to the internet

If your device is impacted you will need to get a new device that's compatible with the Optus 4G/5G networks to stay connected and continue to use your SIM. The easiest way to check if your device is 4G/5G compatible is by having a look at your device specifications in the user manual, or refer to the manufacturer’s website.

Here’s what you need to check to confirm if your device is compatible:

If your device is compatible with the 4G Network 700 MHz (LTE Band 28 or also known as B28 spectrum)
If your device supports 4G VoLTE (which enables voice calls to be made over a 4G network) - including VoLTE emergency calling

If your device does not support one or more of the above, it will no longer work or will have significantly reduced coverage once the 3G network is switched off.

Important - In addition to 3G devices, some recent 4G devices may also be impacted including models that may have been purchased overseas or imported which aren’t configured for Australian networks or do not support 4G VoLTE.

Click here to see some of the devices impacted by this change. Please note this is not a complete list of impacted devices as there are thousands of different devices, models and variants (including devices not sold by Optus).

If you are concerned your device is impacted you can find additional information on our 3G Changes Help & Support Page.

What is AutoRecharge and how can I set it up on Optus Flex Plus?

What is AutoRecharge for Optus Flex Plus? AutoRecharge is the simple solution for automatically recharging your Optus Flex Plus plan on a regular cycle (on the day of expiry) or when you run low on data. Set and forget with AutoRecharge.

How can I set up my AutoRecharge? You’ll need to save a credit/debit card to your account to set up AutoRecharge.

You can set up your AutoRecharge when you activate your service via My Optus app or online (for the $40 and $50 AutoRecharge only plans this will be required to activate your service)
If AutoRecharge is not set up at the time of activation you can set this up at any time via My Optus app.
You can also turn on AutoRecharge by SMS (Text ‘Menu’ to 9999) if you have a saved payment method.

Can I cancel my AutoRecharge anytime?

Yes, you can cancel your AutoRecharge anytime and once your current recharge expires you will no longer be charged. Cancelling your AutoRecharge also means you will no longer be able to use data, make calls or send texts when your current recharge expires unless you recharge manually.
If you are on the $40 or $50 Optus Flex Plus plan and AutoRecharge is cancelled you will need to choose from other available plans when your current recharge expires and as the $40 and $50 plan options will no longer be available.

What is an Activation bonus? When activating a new service on to Flex Plus plans with expiry of 28 days or more, you will get access to bonus data for your first three recharges. Data will revert to your standard inclusions after this period.

Do I get a bonus for activating my AutoRecharge? Yes, customers who activate their AutoRecharge on the $39, $40, $49, $50 and $59 plans will get access to Unlimited Data Weekends for any recharges processed via AutoRecharge. Plus customers can get a $4 discount with AutoRecharge on the $39, $49 and $59 plans. Customers with AutoRecharge will also get bonus data on the $13, $180 and $350 plans. Not available on Flex Plus Casual. Offer available until withdrawn.
