Hi @MohammadTayeb,
If you are under an unlimited plan unfortunately, there is no option to check your internet usage online. Though you can contact our Customer Service team via email (customer service@tpg.com,au) and have it sent directly to the email address registered on your account.
For Mobile usage(s), you may log into your account using your mobile number and password (the password you nominated during registration).
You may check out this article for reference: Checking Your Mobile Usage
Cheers!
