You can add a name of a business to something on mailing header, or you can do a change of responsibility where it's moved to a business account and would be under your employers tax ID, etc.
I know both those options may leave you with some questions, so if you have any, please let me know!
thanks for your support!
Only one question, I tried to change my name in my profile (already done),
but when I check the billing address I can still see my name and not the
company's name. How is it possible?

If you want the bill to have your employer's name instead of yours, you'll want to opt for Lauren's second option and transfer the responsibility over to them. This isn't something you can change on MyT-Mobile.com
