new voice mail and it's asking me to setup voicemail

Exact same issue with my voicemail. Called 611 as was mentioned way above. Was told some of us didn't have a secure pin...or whatever. So to be overly cautious they're having us reset. Bottom line: apparently visual voicemail also has to be re setup. So go there to setup with your 'new' pin. She also said can do from reg voicemail and enter 123 as the code to reset.

I DO NOT WANT a PIN.

What do I do to get this working again after many many many years?

Same about an hour ago, first this happens 

mine did the same thing today

I found a solution!!

Contraseña:
1. Set up your password
2. After setup, it will ask if you want to enter it every time or to bypass the password

Name and Greeting
1. Stay silent for your name recording
2. Decline leaving the greeting message
3. Choose to use your name as your greeting

Go back to using automated greeting:
1. Go back to the main voicemail menu 
2. Select option 3 for “Create a greeting”
3. Select option 5 to use your phone number as your greeting.
 

 

I followed your solution. Worked perfectly like nothing had changed. Thank u so much!

This is a known issue but T-Mobile hasn't informed their call center or first level tech support. I just wasted 45 minutes on the phone before the rep found out about the issue. How can T-Mobile not send out texts and emails BEFORE THEY MADE THIS CHANGE?!  They have our number!

You can call 611 from your T-Mobile line or reach out to T-Mobile by sending them a DM on Facebook or Twitter.

call 611. There’s a ‘real person’ you can talk to.

If you received such texts, it means that your voicemail's PIN is set to the default PIN (last 4 digits of your #). It's really a good practice to change default PIN in general and if you have, you can ignore the notification. On the other hand, you might as well change the PIN. 

You won't lose your voicemails for changing the PIN. If you wan't to be extra careful, might as well back up your voicemails before changing the PIN. There's a lot of guide on how to do so online and a quick search is all you need. I hope this helps.
