For new services, we recommend customers to check first if their service has been installed and activated.
We have created this community article, which contains a video on How to track your TPG service installation
We also send an email notification once the service is activated.
If you have received this email and the service is still not working, we recommend to check if the equipment is properly set up and we have created setup guides for all technologies that TPG use : New Connection Setup Help
In your case, the service has not yet activated and an NBN technician has been booked to completely install the service.
