Welcome to the Community!
Apologies if you are still unable to use the service as expected.
Kindly try the following steps below to see if this will make the service work:
Power cycle the handset. After turning off the handset, battery should be removed. Put it back after at least 10 seconds, then turn on the handset. For handsets like iPhone or any handsets which don't have a removable battery, restart must be done.
Complete a manual network selection
You may need to select another network, then select Vodafone/Optus/Roaming and then turn the phone off and on again.
Change Network Mode/Preferred Network (from 4G to 3G or vice versa).
Do isolation test (try a different handset and/or SIM card)
Should it still not work after performing the troubleshooting steps above, let us know of your best contact time & number via private message so we can organise a call back to be made from our Mobile Technical team.
