Visual Voicemail on Samsung Galaxy S25 requires carrier support and setup through the Phone app. The Galaxy S25 runs One UI, where Visual Voicemail appears as an envelope icon for direct access to transcripts and message lists. Steps vary slightly by carrier like AT&T, T-Mobile, or Verizon.
​

Basic Setup Steps

Open the Phone app and touch and hold the 1 key or tap the Visual Voicemail icon on the keypad tab to start setup. Follow on-screen prompts to create a password, record a greeting, and grant permissions. Carrier-specific apps may be needed; download from Google Play or Galaxy Store if not pre-installed.
​
Troubleshooting Tips

Clear cache/data for the voicemail app via Settings > Apps > search "Voicemail" > Storage. Disable Wi-Fi calling or ensure carrier provisioning; contact your carrier for SIM-specific setup. Update One UI and carrier services for compatibility.
