Before following the steps below, ensure the following:

 Restart the phone.

 Update the device software to the latest version.

 
 
Incoming caller ID
 
  1. Add the contact to your phone book, and confirm their name is spelled correctly there.
  2. Uninstall any downloaded calling apps or caller ID apps.
  3. 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.
  4. If you are roaming on another carrier's network (in the U.S. or internationally), caller ID may not work as expected.
  5. If an incorrect caller ID displays, the caller must contact their carrier to correct any errors in their caller ID registry. Some landline networks cannot display enhanced caller ID. In this case, it may only show some of your city/state, number, or Wireless caller.
  6. If you have no caller ID display at all, you may need to Contact Us to check that it is on your account.
 
Outgoing caller ID
 
  1. If you use a Prepaid account or are on a large government account, it does not include caller ID. Your caller ID displays as T-Mobile Wireless or Wireless Caller when working correctly.
  2. In your phone settings, turn on the Caller ID setting.
  3. If your name has a misspelling or error on all outgoing calls, 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.
