Hi yolicaro! To check the monthly totals for each line, just log in to MyT-Mobile, click BILLING at the top of the page, and in the center of the page you'll see a bill breakdown that shows each line's totals on the right hand side of the box. If you wanted to check the remaining equipment balance for each line's phone, scroll down to the bottom of that same page and click "View Details" in the EIP box.
