Outgoing caller id display

I never use the t-Mobile app on my phone -- My phone is an “added device” on my husband’s account, therefore every time I have tried to use the app to access our account from my phone, it insists on sending an identity verification code to my husband’s phone or email, and my husband is not always available to pass it along immediately for me to type it in.  So I just use my web browser (Chrome) on my laptop if I need to access our account.  

In your web browser, log into your account at t-mobile.com, and then click on "Profile" at the top of the page.  In the Profile page, click the section header titled "Caller ID".  (Or try this link:  https://www.t-mobile.com/account/profile/line-selector/callerid).  From the list, select the device whose Caller ID name you want to change.  By default, the Caller ID for all the devices associated with the account is the primary account holder's name (as it was typed into the system by the salesperson who set up the account).  I used this link today to change the Caller ID on my phone from my husband's first name to my own first, and also to correct the spelling of our last name (on ALL our devices).   

After you make your changes and click "Save", you will get a pop-up at the top of the screen that says you successfully saved the new Caller-ID name.  Repeat the procedure for each device as appropriate.

Nota: 

After you have saved your changes, if you leave the page and then return to it later to confirm the changes, don’t be alarmed if you still see the old data.  It doesn’t mean the changes reverted back to the old info or weren’t successfully saved.  It states on the page that it can take up to 72 hours for the saved changes to take effect (both on the web page and on the device).  So I recommend that you check back after a few days to verify that the info was indeed changed.
