In addition to its internal privacy policies, T-Mobile is bound by FCC regulations regarding cell phone privacy. T-Mobile is required by law to allow anonymous calls on its network, and is not permitted to provide customers with any way to trace or block these calls. This includes performing reverse lookups on these calls. All T-Mobile customers can place anonymous calls by dialing *67.
Caller ID may display a caller's name, but this is not reliable for calls from mobile phones. Calls placed from wireless phones display "Wireless Caller" along with the telephone number.Learn more about Public Records
