Your phone service might be unfinancial so you need to make a prepayment to cover calls not included in your plan.
You can check by logging in to www.tpg.com.au/myaccount. Then View NBN Digital Voice Service Account.
All plans need prepayment. 13/1300 calls are excluded in all plans. Add the smallest value that is available to you. Add prepayment from the page where you see unfinancial.
