Hi @botch ,
Welcome to the community!
Thanks for rasing this to us, here is an article that will guide you on how to add prepaid balance to your TPG mobile service. Please see the link below.
Hello. I got a SMS from TPG says "Your data is now barred as you have insufficient Prepaid balance." Looks like I can still use my data. Do I have to do anything? Thank you for your help.
