How to Set Up Voicemail on Android: Samsung, Pixel & All Phones

Setting up voicemail on Android is straightforward, but the exact steps can vary depending on your handset manufacturer and mobile network. Whether you're using a Samsung Galaxy, Google Pixel, or any other Android device, this guide walks you through everything you need to get voicemail in Android working properly.

Quick Start: Voicemail Numbers by UK Network

Before diving into your phone's settings, it helps to know your network's voicemail number. You'll need this during setup:

• EE: 150
• O2: 901
• Vodafone: 121
• Three: 123
• BT Mobile: 1571
• Sky Mobile: 222

If you're on an MVNO (such as giffgaff, Tesco Mobile, or VOXI), check your provider's website for the correct voicemail access number, as it typically mirrors the parent network.

How to Set Up Voicemail on Any Android Phone

The following method works on most Android devices regardless of manufacturer:

1. Open the Phone app (the default dialler).
2. Tap the three-dot menu (⋮) in the top-right corner and select Settings.
3. Tap Voicemail.
4. Select Voicemail number (sometimes listed under Advanced settings).
5. Enter your network's voicemail number from the list above and tap OK.
6. Dial the voicemail number to complete the initial setup, which usually involves recording a personal greeting and setting a PIN.

That's it — you should now receive voicemail notifications whenever a caller leaves a message.

Setting Up Visual Voicemail on Android

Visual voicemail lets you see a list of your messages and choose which to listen to, rather than dialling in and navigating audio menus. It's far more efficient, especially for business users who receive multiple messages a day.

Google Phone App (Pixel & Other Compatible Devices)

If your device uses the Google Phone app (standard on Pixel phones and available to download on most Android devices):

1. Open the Phone app and tap the Voicemail tab at the bottom.
2. If prompted, tap Set up voicemail or Turn on visual voicemail.
3. Follow the on-screen instructions to create a PIN and record your greeting.
4. Your voicemail messages will now appear as a visual list, with options to play, delete, or read transcriptions.

Note: Visual voicemail availability depends on your network. Not all UK carriers support visual voicemail through the Google Phone app. If the option doesn't appear, your network may not offer it, and you'll need to use the standard dial-in method.

Samsung Galaxy Phones

Samsung devices use their own Phone app by default. To set up voicemail on a Samsung Galaxy:

1. Open the Phone app and tap More (⋮) > Settings.
2. Tap Voicemail > Voicemail number.
3. Confirm or enter your network's voicemail number.
4. For visual voicemail, check whether your carrier's visual voicemail app is pre-installed or available on the Galaxy Store or Google Play Store.

Some Samsung models on supported networks display a Visual Voicemail app in the app drawer. If yours doesn't, you can install the Google Phone app from the Play Store and set it as your default dialler to access visual voicemail features.

Troubleshooting Voicemail on Android

If voicemail isn't working as expected, try these steps:

• Voicemail number not saved: Go to Phone > Settings > Voicemail and re-enter your network's voicemail number manually.
• Calls going straight to voicemail: Check that your phone isn't in Do Not Disturb or Aeroplane Mode. Also ensure call forwarding settings haven't been changed — dial ##002# to reset all call forwarding to default.
• No voicemail notifications: Ensure notifications are enabled for the Phone app in Settings > Apps > Phone > Notifications.
• Visual voicemail not appearing: Restart your device, check for app updates, and confirm your network supports visual voicemail on your plan.
• "Voicemail not set up" error: Dial your network's voicemail number directly and follow the prompts to complete initial setup, including setting a PIN.
