We are making changes to our mobile network and will be closing down older technology from April 2017. The 2G mobile network closure will take place over the following dates:
- WA & NT – 3 April 2017
- SA, QLD, VIC, NSW, TAS & ACT - 1 August 2017
After the shutdown dates, you will not be able to use 2G devices on the Optus mobile network. You will not be able to make or receive call or texts, or access the internet.
3G Single Band devices also use the 2G network in certain areas of the network, so if you have a 3G Single Band device and are outside the coverage of our 3G 2100 MHz network, you will also lose mobile service in these areas when the 2G mobile network closes. For more information on 3G Single Band devices, please see our FAQ below.
Our 2G network was our first ever mobile network, and lets our customers make calls and send texts, with some basic internet connectivity too. But 2G is now an older network technology.
We first launched 2G in 1993 and since then we’ve evolved our network to include newer and faster technologies such as 3G and 4G all of which let you browse the web, download files, stream video and lots more.
After the 2G mobile network closure, your 2G device will no longer work on the Optus mobile network and you will not be able to make or receive call or texts, or access the internet. 3G Single Band devices will also no longer work in 2G areas and the closure of the 2G mobile network may impact your ability to make or receive calls or texts, or access the internet.
3G Single Band is the 3G 2100MHz technology that connects your device to the Optus mobile network. Today, when 3G Single Band devices are used outside of Optus 3G 2100MHz network coverage areas, their service switches to 2G.
After the 2G mobile network closure, 3G Single Band devices will lose coverage when moving into areas once covered by 2G. If you’re currently using a 3G Single Band device, you may need to switch to a 3G dual band (3G2100/3G900MHz) or 4G device – to improve your connection to the Optus mobile network. We recommend checking your device and coverage at www.optus.com.au/coverage.
If you currently have a 2G device, you’ll need to switch to a 3G Dual Band (2100MHz/900MHz) or 4G device, we recommend checking your device and coverage at www.optus.com.au/coverage.
If you have a 2G device, you’ll only ever notice one of these symbols: 2G, Edge, E or GPRS in the top right hand corner of your phone’s screen (next to the signal strength bars) when it’s switched on.
2G phones are usually older phones that are typically best for talking and texting only. Also, older models only feature basic text screens – and that means you may not even see a 2G icon on your phone.
If you see any of these icons: 3G, H+, 4G or LTE on your phone’s screen, then it means your phone is compatible with our newer network technologies. 3G single band phones will show “3G” when in our 3G 2100 MHz coverage areas, but fall back to 2G outside of these coverage areas. The latter coverage areas will be lost once 2G is closed down.
The manufacturer’s manual that came with your device may provide this information.
3G single band (2100MHz) devices use 2G when outside the coverage of our 3G 2100 MHz mobile network. This is often when the 3G single band device is used away from cities and major towns, when on regional roads and highways, or in difficult coverage areas such as basements or underground car parks. If you notice that your phone shows “3G” when you are outdoors in cities and towns, but almost always shows that it is using 2G, EDGE or GPRS in most other situations, then it is likely that you have a 3G single band phone - but make sure you check on our coverage maps or the manufacturer’s manual.
Please be aware than when changing SIM cards, information saved on your old SIM card, including contact numbers may be lost. To avoid this happening, we recommend that you back up any information on your old SIM before replacing or activating a new SIM.
Before you start, first check to see if the SIM card in your current handset fits in to your new phone. If it does, please save your list of contacts to the current SIM card before removing it and inserting it into your new phone.
If the SIM doesn’t fit, please follow the steps to transfer your contacts from your old SIM to the new SIM and your new phone.
Make sure you save your contacts to your existing handset. You may also want to make a handwritten copy of your (key) contacts as a back-up.
Take your new SIM, and put it in your old phone.
Copy your contacts from your handset to your new SIM.
Take your new SIM out of your 2G handset, resize the new SIM to fit into your new handset (if needed), and then insert your new SIM into your new handset.
Please note the steps advised may not apply to all devices.
If your current SIM card does not fit in or is not compatible with your new phone, please make a note of all the contact details you need because you will need to add them into your new device manually.
Any 2G or 3G single-band devices which use a wireless network, including wireless telephony and Optus Wireless Fusion will be impacted.
After the 2G network closure date, any services using a 2G device will be cancelled, meaning you will lose your phone number if you take no action. You will not be able to make or receive calls or access the internet. If you wish to stay connected to the Optus network, you will not be able to keep your current phone number and you will need to check at your local Yes Optus store to find out if you are in a serviceable area for another Optus product.
Alternatively, if you would like to keep your phone number, you will need to move your number to another service provider. This process can take some time, so we recommend that you contact the new service provider as soon as possible and take action at least 3 – 4 weeks before the 2G mobile network closure.
If any of the impacted services on your account are 3G single-band devices, those services will not lose their phone number, however, you may encounter connectivity issues with our network. This may impact your ability to make or receive calls or access the internet.
The only Optus supplied 2G Wireless Telephony or Wireless Fusion device is the SAGEM RL302 Wireless Voice Box. If you are using this device, you will be impacted by the network closure in your state.
If you are using the Optus supplied HUAWEI E960 InZone device, this is a 3G single band device.
All other Optus supplied Optus Wireless Telephony and Optus Wireless Fusion Devices are not impacted by the 2G mobile network closure.
If you are using Optus Wireless Telephony or Fusion with non-Optus supplied Wireless Telephony or Fusion equipment, the manufacturer’s manual that came with your device may provide this information.
If you have a 2G Optus Wireless Fusion or Mobile Broadband service with Optus, it’s important to note that once your Optus Wireless Fusion or Mobile Broadband service is cancelled if no action is taken before the 2G mobile network closure dates, you will lose your Optusnet email account, and you will not be able to access saved emails if you have not linked it with another Optus Broadband account.
Machine to Machine (M2M) devices, such as vending machines or GPS trackers for example, will also be affected by the 2G Network closure unless they are compatible with the 3G/4G mobile network.
If you’re using a 2G or 3G single band machine-to-machine (M2M) device, you’ll need to upgrade to a 4G capable M2M device, also replace any 2G SIM cards and replace any 3G SIMs that are not compatible with your new device. To discuss the solution, speak to your Optus Account Manager, or your M2M hardware provider.
WHAT FREQUENCIES DOES THE OPTUS 2G MOBILE NETWORK USE?
The Optus 2G mobile network uses 900 MHz spectrum.
ARE ALL 2G DEVICES AFFECTED?
Yes, any device that is 2G only will be affected by this change. This will also include business devices that use 2G machine to machine (M2M) technology (such as some EFTPOS / credit card machines).

WHAT WILL I SEE ON MY SCREEN?
If you have not upgraded your 2G or 3G Single Band (2100MHz) device prior to Optus closing its 2G mobile network, you will see one of two things on the screen when you are in an area which previously had Optus 2G coverage:
- “SOS only”, “Emergency Only” or similar message or symbol. This will happen if you are in an area where another mobile network operator has 2G coverage. In this situation, you can make an emergency phone call (police, fire, or ambulance) by dialing “000” or “112”. Your phone will be unable to make any other type of phone call, receive any phone call, or send or receive any SMS or data. Note that Telstra is closing its 2G mobile network down on 1 December 2016; or
- “No service”, an antenna icon with a crossed-line through it, or other similar symbol. This means that your phone has no connectivity to any mobile network and cannot make or receive any phone calls (including emergency calls) or send or receive any SMS or data.
WHAT IF I HAVE A 2G SIM?
While 2G SIMs will continue to work in some 3G devices, older SIMs will not fit into new 4G devices. Optus recommends upgrading your 2G SIM card. SIM replacement is free of charge at Optus stores.
WILL I LOSED MY EXISTING VOICEMAIL SETTINGS AND SAVED MESSAGES IF I UPGRADE MY DEVICE WITH A NEW SIM?
No, once you upgrade and activate your new SIM replacement, all existing voicemail settings and any saved voicemail messages will be retained.
WHAT CAN I DO WITH MY OLD 2G DEVICE ONCE I HAVE UPGRADED?
You can recycle your old 2G mobile and their accessories through the MobileMuster program and drop them off at any Optus retail store www.optus.com.au/shop/stores. The recycling service is free, allowing customers to recycle their old mobiles in a safe and secure way.

WILL I LOSE MOBILE COVERAGE WHEN USING A 2G SIM IN A 3G SINGLE BAND DEVICE?
3G single band devices use the Optus mobile 3G 2100/ 2G 900 network. Customers with a 2G SIM in a 3G single band device may continue to use the Optus 3G 2100 MHz network, however it is possible their Optus mobile network coverage could be reduced (depending on where they use their device) and their ability to make or receive calls or texts, or access the internet may be impacted. This is because, from the 2G network closure dates, the 3G single band device will no longer access a mobile service in current 2G 900MHz locations. We recommend advising customers to check their 3G device and coverage at www.optus.com.au/coverage.
WHAT WILL HAPPEN TO THE INSURANCE POLICY ATTACHED TO MY SERVICE?
After the shutdown date, any services using a 2G device will be cancelled, meaning you will lose your phone number if you take no action and any insurance policies attached to the device associated with that service will also be cancelled.
If any of the impacted services on your account are 3G single-band devices, those services will not lose their phone number or any insurance policies attached to the device associated with that service.
