when you make a call from a T-Mobile device, you may choose to block your Caller-ID information, which you can generally do by dialing *67 prior to dialing the called party's number. Refer to the specific instructions for your communication device regarding Caller ID Blocking for other or different dialing instructions. Please note, however, that Caller ID Blocking does not prevent the display of your information when you dial certain business numbers, including 911, 900 numbers, or toll-free numbers. For more specific information or instructions, you may reach a customer service representative by dialing 611 from your T-Mobile phone or 1-800-937-8997 from any phone
