After 3G network shutdown i can't use my VoLTE-capable phone. Will any "settings changes" help?

[iosd]

According to the manufacturer, my handset is 4G, 5G and VoLTE capable - a fact that seems to be borne out when i use this code to display the phone information: *#*#4636#*#*

And yet, since the TPG 3G network shut down, I have been unable to make or receive voice calls.

In TPG's 3G shut down FAQ, it says, "Some 4G handsets may also need settings changes to be able to continue to make and receive voice calls using our 4G network." https://support.tpg.com.au/3g-network-closure-faq

Could anyone tell me what those "settings changes" would be? I'm keen to try them - and I can't find any guidance on what they might be.

Alternatively, is TPG not able to add my phone to a "whitelist" so that it will work with TPG's 4G network?

Hi @iosd,

Were you able to test and enable the VoLTE on your handset?

Thank you for responding.

No, I haven't been able to enable VoLTE.

When I go to Phone Information via *#*#4636#*#*, I am unable to select the VOLTE Provisioned Flag because it is grayed out.

Is there some other way to enable VoLTE?

Hi @iosd 

Can you share a screenshot of the screen when you dial the code?

Also, what is the make and model of your phone?

Did you purchase it here in Australia or outside?
