Add-on do not get aumoatically renewed as they are one-time purchases. When purchasing an add-on, customers do get prompted to pay for the add-on if there aren't already enough funds in the Public Mobile available balance. The only way to prevent that is the remove the credit card from your Public Mobile account. To do that, you'll need to open a ticket in the chatbot and ask a customer support agent to perform that action. https://widget.telus.tiia.ai/publicmobile/publicmobile.html
@HC4 removing automatic payment for add-ons will also remove it for plan renewals which means you would need to manual pay with vouchers. Is there a reason you are specifically mentioning add-ons?
