For many of us (Galaxy S9) it does not matter if wifi or mobile data is activated. I received notification for the first several weeks, then none for months. Recently I started receiving notifications again (for about a week). Now not working. Xfinity support was less than worthless.
mjr123, thanks for posting about your voicemail issues. What troubleshooting have you done so far? How is your coverage?
Here are my suggestions:
1.) Update to latest iOS 12.3.1 if you didn’t do it yet.
2.) Turn on LTE Voice and Data if not already on.
3.) Turn off WiFi Calling (only use this as necessary)
4.) Turn off WiFi assist (only use this as necessary)
Comcast does not care. They refuse to believe this is a problem and are utterly unable to help with just about anything.
mjr123, thanks for letting us know about your voicemail notification issues. Have you reached out to XFINITY Mobile support yet? I'd be happy to track your case if there is one.
Thanks but I’ve tried it all even getting a different SIM card cause they claimed that was the problem too but not
Shorty030, did you get your mailbox reprovisioned? What about clearing the cache data from the app?
