We only share data with trusted research institutions for public and scientific research purposes.

You can tell us if you want to participate in this data-sharing program by opting in.

We won’t share data that directly identifies you with other institutions.

How and when we share

T-Mobile sometimes receives requests to share data with outside third parties for scientific research or for research that has a public interest focus. When we receive a request to share data for research purposes, we have controls in place to ensure the request is reviewed and that only legitimate third parties will have access to the data. We want to make sure every research project aligns with T-Mobile’s company values, such as providing access to connectivity and technology, and building stronger, healthier, and more equitable communities.

If a researcher or researching institution is permitted access to T-Mobile data, the access will be controlled and shared under an agreement with strict requirements about how the data can used. For example, the third party may only use the data for the approved research purpose and for no other purpose. The third party will also be required to delete or return the data when it’s no longer needed for the specific research project. Finally, third parties must also follow rules about how the data is handled and kept secure.

What data we may share

Phone data

Your device identifiers, usage data, and call data, including times.

Location data

Precise location data based on cellular usage.

Demographic data

Data you provide to us about yourself such as age, gender, etc.

How we protect your data

Data we share when you opt in for public and scientific research won’t identify you directly, even if you choose to share at an individual level. Instead, we might share a unique identifier—basically a string of letters and numbers—that includes data about you like “commuter.” If you allow us to share data in an aggregate manner, this could include something like combining your data with thousands of other users to study how many miles on average people commute from certain zip codes each day.
