You, as consumers, trust T-Mobile to connect you to the world every day, and we’re working hard to earn a place in your heart. A big part of that is maintaining your privacy. We believe you deserve transparency, education, choice, protection, and simplicity. Our goal is to help you take action to protect your privacy.

What’s in this notice

This privacy notice (“notice") explains how T-Mobile, other brands we own, our subsidiaries, and representatives ("T-Mobile" or “we” or “us”) collect, use, share, and protect your personal data when you interact with T-Mobile as a consumer of our services. It also provides you with important information about your personal data choices.

This notice applies to personal data we have about you that identifies, relates to, describes, can be associated with, or could reasonably identify you as an individual. It includes data like your name, address, or email address, as well as less obvious data like demographic data, device and usage data, call records, advertising ID, and location data (where you are located). This notice also applies to sensitive personal data, a category of personal data that includes things like your social security number and account log-in credentials, as well as biometric information.

This notice applies to all personal data we collect and use when you access or use our cell and data services, websites, apps, and other services (our “services”), purchase and use our devices and products (“products”), visit our retail stores or corporate offices, or communicate or interact with us in any way, including mail, email, phone, chat, social media, or in-person.

Some products and services have their own privacy notice. To see the whole list, visit our Privacy Notices. If this notice conflicts with a privacy notice for a specific product or service, the product or service notice applies.

This notice does not apply to data that is not personal, like anonymous, de-identified, or aggregated data, even if it comes from personal data.

We may also share your personal data with third parties when you tell us to or when you use our products or services to interact with third parties, whose separate privacy notices may apply to that data.

With the account holder
We may disclose personal data about an account user to the account holder (the party financially responsible for the account). The primary account holder may also authorize other users to access account information. If a business, governmental agency, or other individual obtains services for you, that entity or individual is our customer, and we may provide personal data about you or your use of our products and services to them or, if they tell us to, others.

Between T-Mobile brands and companies
T-Mobile discloses personal data to its affiliates for things like providing you products and services, and for marketing and advertising and other uses as described in this notice.

To our service providers
We use service providers who may need access to your personal data to do work for us. They’re contractually required to treat your personal data as private (confidential) and to use it only to provide the services we requested. Examples of the service providers we use include print, mail, or email vendors, web hosting vendors, and cloud service providers.

To other third parties
We disclose personal data to third parties for uses described in this notice or for purposes you have requested. For example, we may share data with credit bureaus and similarly regulated entities, banks for device financing, and payment processors to help us provide you with the services you have requested. If you interact with third parties, like content providers who operate video channels or apps through our products and services, we may facilitate the transfer of your personal data for those services. We may also share mobile device identifiers, device and service usage data, and demographics information with third-party advertising partners who may use data to serve ads for T-Mobile and others as described in the Advertising section. These third parties have their own privacy notices that apply to their use of the information we share. For more information, read the Analytics and Reporting article.

To help protect our customers and others from fraudulent use of our network or services, we share personal data (like name, address, account status, SIM change history, and device status) or risk scores derived from such data with entities such as banks or with entities that provide fraud prevention services to T-Mobile.

Caller ID providers
We may disclose your mobile number and name with third parties to enable Caller ID and similar services across multiple carriers when you make a call. We don’t publish directories of our customers’ wireless numbers or make numbers available to third parties for listing in their public directories without your permission. You can ask us to exclude your name from Caller ID by calling customer service. You can also block your number from being displayed temporarily on non-emergency calls. Learn how to block your number.

In a business transfer or transaction
We may disclose or transfer personal data about you as part of a corporate business transaction, like a merger or acquisition, divestiture, sale of company assets, or in the event of insolvency, bankruptcy, or receivership.

We may also disclose personal data to banks and similar entities for the purpose of transferring device financing agreements (or similar agreements) in connection with your device financing.

For legal process and protection
We may disclose personal data to third parties, including government authorities, for legal processes or protection of life and safety where we believe that access, use, preservation, or disclosure of the information is reasonably necessary, including:

  • To comply with laws, regulations, legal process or to respond to lawful requests
  • To enforce or apply agreements, or initiate, render, bill, and collect for products and services (including disclosure to collection agencies to obtain payment)
  • To protect the rights, interests, property, or safety of T-Mobile, our customers, and others
  • In connection with claims, disputes, or litigation
  • To protect you or others from fraudulent, abusive, or unlawful use of these services, and other fraudulent activity
  • In an emergency

How we protect your data

We use administrative, technical, contractual, and physical safeguards designed to protect your data. For example, when you contact us by phone or visit us in our stores, we have procedures in place to make sure that only the primary account holder or authorized users have access.

We can’t guarantee our safeguards will prevent every unauthorized attempt to access, use, or disclose personal data. Be sure to use a strong password to access your information and not one you use for other services. You should also use multi-factor authentication where possible.

Your data choices

We offer consumers in the U.S., Puerto Rico, and the U.S. Virgin Islands choices about their personal data, but your choices may vary depending on the laws that apply where you reside and whether you have a business-to-business account (T-Mobile for Business/T-Mobile for Government). If you have questions, please contact us. Your choices include:

To access your personal data, submit a personal data request. Once we receive your request and confirm your identity, we will disclose to you:

  • The categories of personal data we have collected
  • Specific pieces of personal data we have collected 
  • Our business or commercial purposes for collecting, selling, or sharing personal data
  • The sources from which we collect personal data
  • The types of third parties we disclose personal data to
  • The types of personal data we disclose for business purposes

For multi-line accounts, the Billing Responsible Party or Primary Account Holder submitting an access request will receive account-level data for all lines on the account such as billing and rate plan information. But personal data associated with a particular phone number on the account (data that is tied to the account but is not the data of the Billing Responsible Party or Primary Account Holder) won’t be shared with the Billing Responsible Party or Primary Account Holder and will only be provided to the individual who submits a request for that phone number. If you are not the Billing Responsible Party or Primary Account Holder on the account, you’ll only see information that is associated to your phone number and email that you include in your “Access my personal data” request.

To delete your personal data, submit a personal data request. If you do, we may not delete all your data because certain exceptions may apply. For example, we may keep personal data that is necessary to bill you for services, detect security problems, or troubleshoot or enhance our network. If you request that we delete your personal data, we might not be able to offer some services to you or they might not work the way they’re supposed to or that you’re used to.

If you have a T-Mobile account, you can correct or make changes to your personal data directly through your account portal (“My T-Mobile”). Learn how to correct your personal data. For any changes that cannot be made through your account portal, call Customer Care or submit a correction request.

Authorized Agents
Authorized Agents may act on your behalf by submitting an access, correction, or deletion request. To protect your information, we may request that you verify your own identity before fulfilling a request submitted by your agent.

Verification of your identity
We have to verify your identity before we can give you access to, or delete, your personal data. If we can’t verify your identity, we’ll unfortunately have to deny your request. This is to protect you.

To verify your identity, we’ll need information from you, like your email address and phone number or your T-Mobile ID and password. If you don’t have a T-Mobile ID, you may need to provide your U.S. driver’s license, state ID, or passport. We may also need a photo of your face so we can ensure the photo ID truly belongs to you.

If we deny your request, residents of certain states are entitled to submit an appeal. Instructions for how to submit your appeal will be included in our response explaining why we denied your request.

If you have questions about these choices, please read our privacy FAQs.

Do Not Sell or Share

To tell T-Mobile “Do Not Sell or Share My Personal Information,” visit our Privacy Dashboard or click on the link in our website footers and apps. In this case “sharing” refers to a specific type of disclosure under certain privacy laws that relates to advertising activity, including “targeted advertising.” An example of a sale or “share” of information is when we disclose information about you (like when you’ve visited our sites) tied to unique identifiers, like device IDs, with third parties for targeted advertising. When you tell us not to sell or share your personal information, we won’t disclose your personal data for these purposes. Of course, not all disclosure of personal data is a sale or share, like when T-Mobile provides your data to service providers to deliver our products and services.

T-Mobile recognizes Global Privacy Control (GPC) signals, which are a way for you to set a “Do Not Sell or Share” preference at the browser level. This means that if your browser or browser extension has GPC enabled, our websites will automatically recognize that signal and opt you out of the “sale” or “share” of your personal data.

To learn more, read the Do Not Sell or Share My Personal Information article.

Profiling and automated decisions

You can tell us not to use your personal data for certain kinds of “Profiling” that we might do in the future by visiting our Privacy Dashboard to opt out. “Profiling” is a specific type of activity under certain privacy laws and generally refers to the automated processing of personal data to evaluate, analyze, or predict certain personal aspects about your performance at work, economic situation, health, personal preferences, interests, reliability, behavior, location, or movements. You can opt out of having Profiling used for future decisions that produce legal or similarly significant effects about you. We don’t use Profiling to make those kinds of decisions now.

Marketing communications

If you don’t want to learn about products and services we or our partners offer, you can adjust your marketing communications preferences in our Privacy Dashboard. Not all of our communications are for marketing, and you’ll continue to receive service messages for your products and services (like bills, transactional notices, customer service, etc.). To learn more, read the Your marketing preferences article.   

Advertising and analytics choices

T-Mobile data use for the Ad Program
Under T-Mobile's Ad Program, T-Mobile will use certain data (1) for Analytics and Reporting (2) to deliver Relevant Ads, and (3) to deliver Personalized Ads and Offers.

Analytics and Reporting
For Analytics and Reporting, our program is designed to use information from your device (i.e., app usage data like app name, installation status, how often an app was opened and zip code) and data from your use of T-Mobile products and services, such as self-declared data like age range (e.g., 25-34) and gender, to prepare aggregated business and marketing reports that we use and share with other companies. These reports do not identify you personally. One example might be a report showing how often a game was downloaded in the past year across large numbers of users. We will use this data unless you tell us not to by opting out.

Relevant Ads
For Relevant Ads, T-Mobile will use and analyze app usage data from your device like app name, app installation status, and how often an app was opened, self-declared data from your use of T-Mobile products and services such as age range (e.g., 25-34) and gender, and high-level app usage data from your T-Mobile broadband to create models and inferences (e.g., sports lover, cooking enthusiast). To illustrate what high-level app usage data from your broadband is used, we process the name of an app you opened, like a recipe app, and how long you spent in that app, but we do not see any additional information, like, for example, that you looked at Italian and Thai recipes.

We do not use app usage data to select advertisements, we only use your mobile advertising ID (MAID) and the models and inferences created from the app usage data. We and our advertising partners will use your MAID from your device and data from third party partners to deliver Relevant Ads to you. We will use this data unless you tell us not to by opting out.

When we share MAIDs and inferences with third parties, it is not tied to your name or information that directly identifies you. 

Personalized Ads and Offers
In addition to the data used for Relevant Ads, with your consent, we and our service providers will use precise location and other self-declared data you provide to us such as age range (e.g., 35-54), gender, interests, and survey responses from your device and top-level domain information about your web browsing activity from your broadband data to provide you with more Personalized Ads and Offers. To illustrate, we process the top-level name/URL of the website you visited, such as a major retail website, but we do not look at what web pages within that site you visited (e.g., clothes or toasters). We won’t use this data unless you opt-in and we’ll stop using it if you opt-out.

We don’t use or share Customer Proprietary Network Information (“CPNI”) for advertising unless you give us your express permission or as allowed by law to advertise certain T-Mobile products or services.

We also do not use information from T-Mobile prepaid accounts or Assurance Wireless accounts for advertising. We also do not use information for advertising from accounts where a corporation or government agency is responsible for paying the bill. And if we know information belongs to a child, we don’t use it for advertising.

For more information about data we use and share for the Ad Program, visit our Privacy Dashboard. When you opt out of the sale or sharing of your personal information from our website footer or opt out using our Privacy Dashboard, your info will not be used for Relevant Ads unless you have provided your opt-in consent for Personalized Ads and Offers. To learn more about how your choices, visit our Privacy Dashboard.

Ads on your mobile device, computer, or other devices
You can get instructions on how to opt-out of targeted ads served by most advertising networks that use cookies, Ad IDs, and similar technology by:

You can also take steps to manage targeted ads through your system settings. Resetting your device’s mobile advertising ID does not opt-out your device from targeted ads, but data associated with your prior mobile advertising ID will not be linked to your new identifier through the device. Also, if you reset your device’s mobile advertising ID your prior opt-out choices will not apply to the new ID. To maintain your opt-out choices, you’ll need to opt-out again. These opt-outs will not impact “contextual” advertisements (e.g., a sporting goods advertisement on a sports-themed website) or ads we place on our own websites and apps based on your activity on those sites and apps.

Cookies choice
Most web browsers can be set to detect or reject cookies. Each browser is different, so check the “Help” menu of your browser settings to learn how to change your cookie preferences. If you reject cookies, some things on our websites may not work properly. To learn more about cookies, read our Cookies and tracking article.

Ads on social media
We may work with certain social media websites or platforms (such as Facebook or Twitter) to serve targeted ads to you as part of a customized social media campaign. You can opt-out of receiving customized ads on your social media platforms by changing your ad preferences on those platforms. We don’t control those platforms or your ad preference settings on them and recommend regularly visiting your ad preference settings to ensure they remain accurate.

Some opt-out mechanisms described in the Advertising choices section and the “Do Not Sell or Share My Personal Information” mechanism for T-Mobile websites described in the Do Not Sell or Share section rely on cookies to retain your opt-out preferences. If you reject or erase cookies, your opt-out choices and Do Not Sell or Share requests may not work correctly, and you may need to perform the opt-out again.

Location data choice
We collect your location data to provide you with our wireless services. For certain non-essential activities, such as advertising, we request your permission before using precise location data associated with your identifying information. We don’t use or disclose precise location data for advertising unless you give us your express permission. For more information, read our Cookies and tracking article. If you have previously consented to these uses, you may revoke that permission at any time through your device’s operating system location preference controls or, in some cases, the app settings. You may also follow the standard uninstall process to remove the app from your device.

Privacy requests received

As a part of T-Mobile's ongoing commitment to transparency about our privacy practices, we share information annually on how many privacy requests we receive. The data below is for the year 2022.

California residents

Under the California Consumer Privacy Act (CCPA), Consumers who are California residents have personal data rights, including the right to access, correct, delete, and stop the sale or sharing of personal data. Although the CCPA only provides these choices to California residents, T-Mobile, as an entity doing business in all 50 states, extends these benefits to residents in all U.S. states.

Of course, if you do exercise any of these rights, T-Mobile will not treat you any differently. You can exercise your personal data rights within our Privacy Dashboard.

Categories of personal data collected and disclosed 
For business purposes in the preceding 12 months is described in What data we collect and When we share your data.

Business or commercial purpose for collecting personal data
This is described in How we use your data

Categories of sources of personal data
This includes information you provide us, that we collect and infer when you use our products and services and provided or purchased from other sources. For more information, see How we collect your data. 

Categories of third parties with whom we share personal data
This is described in When we share your data

Sales and Shares of personal data

California law requires us to tell you that in the past 12 months, T-Mobile (which also includes Sprint) sold (as “sale” is defined in that law) the following categories of personal data for the following reason: We shared device identifiers and internet and electronic network activity to facilitate online advertising. This means that a unique, resettable number that identifies your device was linked to online activity and shared with others who use that data for advertising and analytics purposes (like advertising networks, data analytics providers, and social media platforms). For Sprint customers, we used to share location and usage information with other companies in a way that does not directly identify you for their use in creating aggregate reports. For more information, read our Do Not Sell or Share article. T-Mobile doesn’t knowingly sell or share the personal data of children under 16. Don’t want your data sold or shared? Set your Do Not Sell or Share preference in our Privacy Dashboard or click the link in our website footers or apps.

Shine the Light

Under the Shine the Light law, California customers may request information about whether a business has disclosed personal data (as defined in that law) to any third parties for their direct marketing purposes. We don’t do that without your permission.

Maine customers

We will not use, disclose, sell, or permit access to your personal broadband data unless it’s allowed in Maine. Maine customers have rights that they can exercise in our Privacy Dashboard. 

Children’s data

We know it’s important to treat data parents and guardians tell us is from children under 16 and data from products and services we design for children carefully. The Children’s Privacy Notice explains what we do (and don’t do) when it comes to children’s data. Generally, if you allow a child to use our products or services by providing them with a device or other access associated with your account, any personal data associated with their use will be treated as your personal data. If you’re the parent or guardian of a child using a T-Mobile branded service, T-Mobile is currently testing the ability to designate the line as a Kids’ Line. To learn more about Kids’ Lines including how to set one up, please see the Children’s Privacy Notice.

This privacy notice and the Children’s Privacy Notice don’t apply to data collected by third party apps and websites, and we encourage parents to review the terms and policies of apps and websites before allowing children to use them. For more info, read the Family Controls and privacy article.

For specific information about kid products like SyncUP KIDS Watch and FamilyMode, please see the Children’s Privacy Notice.

Other important info


You may see T-Mobile and other advertisements on your devices, whether you’re connected to our network or not. These ads may be targeted to your device based on information that we, the advertiser, and other third parties have about your behavior or interests to make them more useful to you. These ads are called interest-based or targeted ads.

T-Mobile works with third parties, including advertising networks, which collect information about you through devices, websites, and apps, serve ads for us and others, and measure their effectiveness. The advertisers and third parties that provide these ads may use cookies, code, and web beacons or use mobile device identifiers and similar technologies for these activities. For example, third parties like Google Ad Manager and Nielsen may use technology to collect data to deliver, personalize, and measure ads for some of our products and services. This technology allows tracking of device activity over time across online properties. The advertisers and advertising networks’ use of these technologies and of the information collected is covered by their own privacy notices and those of the sites where they operate. T-Mobile may also use its own online advertising services in connection with these ad activities. You can opt out of receiving targeted ads through your T-Mobile.com account.


We may also partner with analytic service providers like Google Analytics to help track your use of our products and services. To learn more about how Google collects and processes personal data, visit Google Privacy & Terms. For additional details, see the Cookies and tracking article. To learn more, read the Your privacy around the web article. For more information on our ad program and your choices, go to the Advertising choices section.

Do Not Track

Do Not Track signals are a web browser setting or mechanism used to indicate that you do not want your online activity tracked. Because there is no universal standard of how to apply that setting, we currently do not honor them. However, we do honor Do Not Sell or Share requests.

Geolocation data

If your mobile device is turned on, our network is collecting data about where it is. We may use, provide access to, or disclose this network location data without additional, specific permission to provide and support our services. Examples include to: 

  • Route wireless communications
  • Operate and improve our network and business
  • Detect and prevent fraud
  • Provide information to emergency responders about where to find you when you call public safety agencies, including through 911 or similar emergency services numbers
  • Comply as required by law

Subject to your settings, we and others may also use geolocation data to provide location-based services (like SyncUP PETS), or to personalize your experience and ads. To learn more, see our Cookies and tracking article.

Internet of Things

We provide connectivity to Internet of Things, or IoT, devices and services offered by other companies. We collect basic information about the information flowing over our network. However, if you’re a customer of a T-Mobile IoT service, we, and our apps providers, also collect information from the IoT device and any related app to support the service. The information varies depending on the service but may include personal data like contact information and location, audio, and device activity and measurement data.

Data Retention

We retain your personal data for business or tax needs, or legal reasons. We set our retention periods based on things like the type of personal data, the business purpose for which it was collected, and legal obligations to retain certain kinds of personal data.

Technologies in retail stores

In some of our retail stores, beacons have been deployed and we receive aggregate reports (none of which identify any individual or device) from these stores regarding store traffic that uses information collected from beacons through mobile apps. We may also use technology that tracks aggregate traffic patterns and wait times in our stores using Wi-Fi and Bluetooth identifiers (e.g., a MAC address). We’ll provide a notice at each location where we use this technology. If you don’t want your device used this way, opt out at any time by entering your MAC address at Smart Place Privacy. 

Unaffiliated third parties

Our products and services provide links and access to others’ websites, content services, and apps, and allow you to share personal data with others and to use products and services that T-Mobile doesn’t control. These third parties may collect your personal data. For example, we may offer social sharing features and other integrated tools (such as the Facebook “Like” button), which let you share actions you take on our products and services with other media, and vice versa. Your use of such features may enable the sharing of information with your friends or the public, depending on the settings you establish with the entity that provides the social sharing feature. Look for their privacy notices to see what personal data they collect, share, and use, as we of course don’t have any control over those practices.

For additional details, read our Your privacy around the web article.

U.S.-based organization

T-Mobile is headquartered in the United States and our data processing mostly takes place in the United States. Your personal data may be transferred to, processed, and stored in the United States or in other countries where our affiliates or service providers process data. T-Mobile does not offer products or services directly to consumers in the EU or UK.

International data privacy

T-Mobile's international services, previously provided by Sprint and now part of T-Mobile for Business, are directed to business customers. Users of T-Mobile's international services are typically employees of those business customers, or prospective business customers, and personal data that we collect will generally be limited to information collected or generated in a business context. 

Future changes

We keep this privacy notice up to date. When we make changes, we’ll let you know by updating this notice and the date at the top of this page. In addition, prior to making a material change to how we use or share your data, we’ll also reach out to you (e.g., by text or email or with your bill). If you keep using our products and services after we notify you, we’ll take that to mean you’re fine with the changes for any new data we collect. Those changes will not apply to previously collected personal data unless we get consent from impacted consumers.
