You're welcome Llib. Have a lovely afternoon and don't hesitate to reach out here again in the future.
200 dollars of extra charges on my daughters phone in 4 days, you send her a text message to say 50, 100, 150 but not the account holder, I will be contesting the charges.
The account holder can definitely set up the alerts to go to a nominated number of their choice.
Please see our Mobile Usage Alerts help and support page for more info.
