Calling services

    Learn about 411 directory assistance, caller ID, call waiting, and call forwarding.


    411 directory assistance

    411 directory assistance allows you to reach a live operator for directory assistance from your T-Mobile phone.


    To connect, dial 411 and send the call. Each 411 call costs up to $1.99 (plus talk time for Prepaid plans). Three directory listings are included per call.



    Call forwarding

    Call forwarding allows you to forward your incoming calls to another number. You can set it up to forward all your calls immediately. Or, you can set it up to forward if you don't answer the call, if your phone is turned off, or if you're out of signal range.


    Be aware of the following when using call forwarding:


    • You can't forward calls to international numbers.
    • You can only forward calls to 10- or 11-digit numbers.
    • Forwarding while roaming depends on the host country's network capabilities.


    To set up call forwarding, visit the Devices page. Select your phone, then go to Calls > Call forwarding to view the steps.



    Call waiting

    Call waiting and call hold are used together. If you receive an incoming call while you're on the phone, you hear a tone letting you know another call is coming in. If you answer the incoming call, the first call is automatically placed on hold. You can then switch between the calls, or join the calls using conference calling.


    For Pay in Advance (Prepaid) plans, minutes are deducted for each incoming call when using call waiting.



    Caller ID

    Caller ID is a free service that lets you know who is calling by displaying their number on your phone. If the caller's contact information is stored in your phone, you see their name as well. Because of landline limitations, some numbers may not display on Caller ID.


    If you have a landline phone, you most likely have Enhanced Landline Caller ID. If not, a combination of the caller's city, state, or "Wireless caller" and their mobile number appears on the caller ID.



    Name ID

    For a small monthly fee, you can add the Name ID feature to your account. Name ID lets you see the name and number that's calling, even if you don't have the caller's information stored in your phone. This service is available if you're on our Simple Choice™ Plan or Simple Choice™ North America Plan. You can add Name ID to your line by changing your services on My T-Mobile.


    Name ID app

    You can also use the Name ID service using the T-Mobile Name ID app (although it's not required), and it comes preinstalled on Android devices that support the app. Learn more about T-Mobile's Name ID app.



    Communication Bundle

    For a small monthly fee, you can add the Communication Bundle feature to your account. The bundle provides both the Name ID and Voicemail to Text services in one bundle at a savings over having the features separately. While Name ID lets you see the name and number of unblocked callers that aren't in your list of contacts, VTT delivers voicemails to your phone as a text message. This bundled feature isn't available for Pay in Advance (Prepaid) accounts. You can add the Communication Bundle to your line by changing your services on My T-Mobile.


    Anonymous callers

    When you receive calls, the telephone number of the caller is generally delivered to your mobile device, allowing you to identify the number (and the name you entered into your contacts) of a caller before answering. However, the FCC has mandated that mobile carriers allow callers the ability to block their Caller ID information and thus place “anonymous” calls. T-Mobile is obligated to honor the privacy of the caller in these circumstances. Of course, you may choose not to accept such calls, but we cannot block the call or override the privacy choice of the caller.


    Before you make a call, you can choose to block your Caller ID information. Simply dial *67 prior to dialing the called party’s number.
