I just upgraded from Galaxy S22 to S25 PLUS on AT&T and having trouble setting up Visual Voicemail.
It seems that the app cannot access/process my account information in my AT&T Voicemailbox.
Here is what happens:
Initial setup screen, tap "Start". The little dots spin for about 30 seconds with the message "Please wait while we check your account information".
Next thing that pops up is Voicemail Setup with the following:
The app hasn't received setup information, but you can still attempt to set up Visual Voicemail * Tap the Setup button below to set up Visual Voicemail
* Enter your mailbox
* End the call
* Continue setting up Visual Voicemail
Tapping the Setup button successfully calls my Voicemail Box, which tells me how many messages I have, etc. just like calling in directly; including new voice messages that have been called in for testing purposes. Upon ending the call it says "Please wait while we check your account information."
Which leads to the next screen that says:
An account verification hasn't been received yet.
* Verify your network connectivity
* Call your voicemail again and make sure you access your mailbox successfully
* Contact support to verify that your Visual Voicemail service is activated.
This is an endless loop that goes back to the top.
I know I have made at least 20 attempts all with the same result.
The voicemail icon on the telephone keypad brings me to the top of the above endless loop.
I just completed a 1 hr 45 min call with AT&T Support (Level 1 and Advanced Technical Support), followed by a 1 hr 30 min call with Samsung Support.
Both of which were unable to resolve the issue and both pointing the finger at each other.
The AT&T team admitted this is the first they heard of this issue.
The Samsung agent conferred with the team on multiple occasions.
Incidentally Visual Voicemail cannot be uninstalled (that option doesn't exist) it can only be "Removed"
Also there is nothing in Play Store for Visual Voicemail for AT&T or anywhere on the web, except for 2 older versions that are incompatible with the S25 PLUS.
Any help would be greatly appreciated, even if it can be determined who is responsible for this.
