Welcome to TPG Community @6152713!
To make calls outside your plan inclusion, a pre-paid balance is required. Here's how you can top up Your Home Phone Optional Prepaid Balance
If you have a prepaid balance but still unable to make a call, you can check out Troubleshooting outgoing calls for NBN Home Phone & Digital Voice
If none of these help, send us a private message and confirm your phone number so we can have a closer look at your account.
Regards,
Aubrey
