This is a user support forum and not even the handful of T-Mobile moderators here have access to any account information. Either call 611 on your T-Mobile phone or contact via one of these options Contact Us
The other option is to log into your MyT-Mobile account on a computer, go to billing tab, then at the bottom you will see a box with your EIP(s) which you can click on and see the balance for any or all EIP's.
