Caller ID is a free service that let's you know who is calling by displaying their number on your phone. If the caller's contact information is stored in your phone, you'll 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 displays on the caller ID.
For a monthly fee, Name ID lets you see the name and number calling, even if you don't have the caller's information stored in your phone. This service is available to our Simple Choice customers. You can add Name ID to your line by changing your services on My T-Mobile.
