Setting Up Voicemail On Samsung S20: A Quick Guide

Voicemail helps you capture missed calls, but many users struggle to find the correct Samsung S20 settings. This guide shows every reliable way to set up voicemail and helps you fix common issues quickly.

But before you start, confirm your carrier supports voicemail on your line and that your S20 connects to the network normally. This avoids errors when you open the voicemail menu.

Set up voicemail on the Samsung S20 using the Phone app

Open the Phone app and tap Settings. Tap Voicemail and verify the voicemail service and number so your S20 routes calls to the correct inbox.

Next, press and hold 1 to call voicemail. Most carriers ask you to set a password or record a greeting on your first call.

Set up visual voicemail on the Samsung S20

Open the Phone app and tap the Voicemail tab if your carrier supports it. Check for the Visual Voicemail option and select it if it is available. Now, follow the onscreen instructions to complete the setup.

Note that some carriers require you to install their Visual Voicemail app from the Play Store.

Set up voicemail for Verizon, AT&T, T-Mobile, and Google Fi

While the process of setting up voicemail on Android remains largely the same, each carrier uses its own voicemail number and setup process. Follow the steps that match your provider.

Verizon voicemail setup steps

Press and hold 1 to call *86 and complete initial setup. Verizon Visual Voicemail downloads automatically on many Samsung S20 devices.

AT&T voicemail setup steps

Press and hold 1 and follow the prompts to create a password. AT&T may require you to set security questions before you record a greeting.

T-Mobile voicemail setup steps

Hold 1 to call 123, then follow the spoken instructions. If Visual Voicemail fails to appear, install the T-Mobile Visual Voicemail app.

Google Fi voicemail setup steps

Open the Google Fi app and select Phone settings. You can customize greetings and enable transcription directly from the Fi interface.

Use Google Voice as an alternative voicemail

Google Voice gives you cloud-based voicemail with strong transcriptions. You can route missed calls to Google Voice instead of your carrier inbox.

Activate Google Voice voicemail routing

Open the Google Voice app and go to Settings. Enable Voicemail via Google Voice to redirect unanswered calls to your Google Voice mailbox.

Turn off Google Voice if you want to return to carrier voicemail

Disable call forwarding inside Google Voice and restart your S20. This restores your original carrier voicemail routing.

Set up voicemail on dual-SIM Samsung S20 models

Dual-SIM and eSIM devices route voicemail differently. You must select which SIM handles calls before voicemail works correctly.

Choose the correct SIM for voicemail

Open Settings and select SIM manager, then set the default calling line. Your S20 attaches voicemail to whichever SIM handles outgoing calls.

Understand limitations of voicemail on travel or secondary SIMs

Some prepaid or travel SIMs do not support Visual Voicemail. You may need to rely on basic voicemail dialing instead.

Troubleshoot voicemail not working on Samsung S20

If voicemail does not activate or fails to receive messages, a few quick fixes usually restore it.

• Check and reset the voicemail number: Open the Phone app settings and confirm the voicemail number matches your carrier. Resetting it helps if messages fail to load.
• Disable call forwarding conflicts: Call forwarding often overrides voicemail. Open the Phone app’s Call settings and turn off unconditional and busy call forwarding.
• Give the Phone app permission to access voicemail: Go to Settings > Apps > Phone and enable permissions such as Call logs and Notifications. Visual Voicemail depends on these permissions.
• Reset network settings if voicemail cannot activate: Go to Settings > General management > Reset > Reset network settings. This restores carrier defaults and often fixes voicemail routing problems.
