How to add a data block to your TPG mobile service

Community Manager

This article will explain what Mobile Prepaid Balance is and how you can use it to buy additional data blocks once you run out of data.


Check out our video guide or follow the steps below


What is Mobile Prepaid Balance?

Mobile Prepaid Balance is an optional prepayment amount that you can choose to keep in your account. It will be used to pay for any usage outside of your plan’s included value.


Common reasons customers use their Mobile Prepaid Balance:

  • If you reach your monthly included data, $10 will be automatically deducted from your Prepaid Balance to add a 1GB extra data block.
  • If you make an international call without any free international minutes remaining on your plan, the call charges will be deducted out of your Prepaid Balance.


What is my default Prepaid Balance?

By default, everyone’s Prepaid Balance is $0. You can choose to add more Prepaid Balance at any time, or you can choose not to ever keep any Prepaid Balance in your account.


How to add Prepaid Balance to my account?

When you sign up for TPG Mobile, you have the option to add a Mobile Prepaid Balance amount.


If you’ve already signed up, you can easily add Mobile Prepaid Balance via TPG My Account.


1. Log in to TPG My Account at


  • You’ll need to log in with either your 7 digit Customer ID or your Mobile Number, plus your password
  • If you’ve forgotten your password, you can securely reset it at


2. Click on 'View All Mobile Service Accounts'




 3. Look for your Mobile Number (you may need to scroll down if you’ve done a few plan changes). Make sure you find the entry with the "Active" Status. Then click on 'Add Prepaid Balance'.




4. Choose your preferred Prepaid Balance amount then click the "Submit" button





 The Prepaid Balance that needs to be added for more data is $10 for every 1GB block.

The maximum extra data you can have per month is 5GB.


What happens if I have $0 Prepaid Balance?

In this case, you won’t be able to make any usage that is outside your plan’s included value. It also means that if you reach your included data (e.g. you use 12GB of your 12GB monthly data quota) you won’t be able to use any mobile data until your next monthly billing cycle rollover.


Maintaining $0 Mobile Prepaid Balance suits many of our customers who want the peace of mind to know that they won’t incur any charges for excess usage and will only pay their plan fee every month.

Hi @4833781


Welcome to TPG Community! 


We've managed to pull up your account using your community details and at the moment, your payment for $50 is currently in progress via direct debit. It will take 3 to 4 working days for the payment to clear.
Note: A $10 rejection fee and a possible dishonor fee from the bank will apply in case the payment is rejected.


Let us know if you need more assistance. 


Best regards,
