Voicemail stopped working

Good afternoon @askewdb, thanks for reaching out to us. 

We can certainly understand how important being able to access your voicemail is, and apologize for the inconvenience this has caused you. It would be a pleasure to assist you in investigating this issue.

I see you mentioned you have recently upgraded from a Samsung Galaxy S7 to a Samsung Galaxy S21, and have already attempted troubleshooting. To ensure we are finding the right solution, please may you provide or answer the following:

• How long ago did you activate your Samsung Galaxy S21?
• Are you using the old sim card you had inserted in your Samsung Galaxy S7?
• What current Software Version do you have on your device? Directions: Go to Settings > Scroll down to bottom, Tap Software Update > Tap Show Software Update History. If you have not already checked for new Software Updates, please Tap Check For System Update under the same page you see software update history. 
• Have you tried uninstalling/ reinstalling the voicemail application and turning on data when attempting to access the app?

If you have any other questions and concerns, please do not hesitate to reach back out us. Thank you for being a part of our AT&T family, we look forward to speaking with you soon.

Hi, did you manage to fix the problem?

How does the voicemails show up on Google voice ?
Is it a stand alone type app or do they come in as a text message ?

Hello there?

Go to Phone>Settings>Voicemail and make sure all details are legitimate. Check the voicemail number and service provider. If you find any incorrect settings, revert them to the original settings and save them
