There could be several reasons why your mobile isn’t connecting to the 5G network. Try the following troubleshooting steps:
1. Are you able to access the Optus network?
Check whether you're able to connect to the Optus network.
You can see which network you're connected to in the top left corner of your mobile phone's home screen.
If you cannot see 5G, 4G or 3G, there may be an issue preventing you from connecting to the Optus network. See our mobile phone internet troubleshooting article for more help.
If you're able to connect to 3G or 4G, but cannot connect to 5G, move on to step 2.
2. Are you using a 5G capable device?
Not all mobile phones are compatible with the 5G network. See the above FAQ for a list of 5G capable devices.
3. Check 5G coverage is available in your area
The Optus 5G mobile network is currently only available within selected Australian suburbs
4. Turn your mobile data off and on again
