As a telecommunications carrier, we collect and maintain information about our customers’ voice calls. We also use data about voice calling to identify offers for T-Mobile calling plans, protect against fraud, and to respond to emergencies. Because data about calls you make is sensitive personal information, Congress and the Federal Communications Commission (FCC) have created rules that we follow to protect your privacy.
Much of the information we collect about your voice service is called customer proprietary network information or CPNI, which includes:
- Phone numbers called
- Date and time of calls
- Number of minutes on call
- Phone-related purchases like call-waiting
- International calling
Your CPNI doesn’t include your name, address, phone number, or the content of your phone calls. Phone call content has stricter protections under wiretapping laws. To learn more about how T-Mobile collects information regarding phone calls, visit our T-Mobile Privacy Notice.
