A lot of things can affect your Caller ID name, number, or both from displaying correctly. Entries in your contact list, device type, or even the available features on your account can change your Caller ID display. Let's check them out. 

 

If you're looking to supercharge your Caller ID and get the power to block unwanted calls and texts, check out T-Mobile Scam Shield app.

Before following the steps below, ensure the following:

 Restart the phone.

 Update the device software to the latest version.

 
 
Incoming caller ID
 
  1. Check if you have T-Mobile free Caller ID enabled, use the T-Mobile Scam Shield app to add the $0 feature or Contact Us
  2. Uninstall any 3rd party downloaded calling apps or caller ID apps.
  3. Add the contact to your phone book, and confirm their name is spelled correctly there.
    •  If you are roaming on another carrier's network (in the U.S. or internationally), caller ID may not work as expected.
    • If you have no caller ID display at all, you may need to Contact Us to check that it is on your account.
    • The Caller ID name field is limited to 15 characters.

If the incoming call shows Unknown or Unknown Caller, the caller's phone or network might be set to hide or block the caller ID for all calls.

 
Outgoing caller ID
 

By default, only your outgoing caller ID number will display. If you want your caller ID Name to display, use the T-Mobile Scam Shield app to add the $0 feature or Contact Us.

  • If you use a Prepaid account or are on a large business/government account, it does not include caller ID.
  • Your caller ID displays as T-Mobile Wireless or Wireless Caller when working correctly.

To check if caller ID is turned on:

  1. In your phone dialer settings, turn on or display your Caller ID setting. Visit the Devices page, select your device, and look for steps to display Caller ID.
  2. If your name has a misspelling or error on all outgoing calls, use the T-Mobile Scam Shield app to check the spelling or Contact Us to correct the account's caller ID registry. 
    • T-Mobile needs to make these changes manually with our caller ID vendors.
    • Changes take up to 72 hours to complete.
