ATT is horrible. I got my phone replaced, a Samsung S25 Ultra, through my warranty program and due to it not coming directly from ATT, they will not support Visual Voicemail or ATT video calling.
My S23 Ultra from ATT contained a lot of unnecessary apps, bloatware. I dealt with it since the phone was basically free three years ago. Well it malfunctioned recently and had it replaced through my warranty program. The warranty company gave me the S25 Ultra, Samsung SM-S938U1, which is the direct from Samsung variant. Well, ATT will not unlock their Visual Voicemail app in the Google Play Store to be compatible with direct from manufacturer devices. What a load of shit. I never had this issue with Verizon or T-Mobile in the past. This company is so sideways.
Please, does anyone know any work arounds to get visual voicemail? Within the Google Phone app, Visual Voicemail is greyed out and it will not let me toggle it on. I called ATT and they have zero solutions other than to buy their bloatware phones from them.
First pic is the Google Phone App toggle, the second and third Pic is the non compatible ATT Visual Voicemail app in Google Play.
