Ethics and integrity guide everything we do.

If something seems off, talk to your manager, skip-level manager, or HR employee success partner. If that’s not an option or doesn’t apply, use the T‑Mobile Integrity Line to report your concern. The important thing is to reach out to someone who can help.

Speak up.

If you're aware of potential misconduct, or have a concern—reach out.

Reporting is simple.

Choose whichever option you’re most comfortable with, even to just ask a question.

The Integrity Line is a 24/7 resource managed by an independent third party. If you choose to report anonymously, your identity will not be known to the third party or T‑Mobile.

Every report is taken seriously.

Know that your report will be treated fairly and promptly, no matter who you are or what you're reporting.

We’ve got your back.

T-Mobile does not tolerate retaliation—ever. Employees who retaliate against someone for raising a concern in good faith will be subject to discipline, including termination.

T-Mobile leaders set the tone.

We expect our leaders to create a safe environment for employees to raise concerns.
