I’ve been in situations where voicemail stops working on my Android phone, and it can be frustrating. Whether it’s not receiving voicemails, delayed notifications, or the voicemail app crashing, these issues can leave you missing important messages.
From my experience, the cause is usually a network configuration issue, carrier setting mismatch, or a corrupted voicemail app. So, if you’re facing this problem, I’ll walk you through every possible fix, from basic troubleshooting to advanced solutions, including carrier-specific fixes and hidden tricks that worked for me.
Quick Summary
If you don’t have time to go through the whole guide, here’s a quick rundown of the key fixes:
- Restart your phone and toggle Airplane mode.
- Update or reinstall the voicemail app.
- Clear cache and reset voicemail settings.
- Ensure call forwarding is disabled (##004# works for most carriers).
- Reset your network settings if nothing else works.
- Try carrier-specific codes like #793# for T-Mobile or *86 for Verizon.

- Contact your carrier for a backend reset if the problem persists.
Now, let’s dive into the details.
How Voicemail Works on Android
Before fixing voicemail issues, it helps to understand how Android voicemail functions.
Carrier-Based vs. Visual Voicemail
- Traditional Voicemail: Managed by your carrier, stored on its servers, and accessed by dialing a number.
- Visual Voicemail: Uses an app to download and display voicemails as audio files, syncing messages over mobile data.
Wi-Fi vs. Mobile Data
Note that some voicemail apps require mobile data to be enabled for full functionality, even if your carrier manages your messages.
If your Android voicemail isn’t working, you might notice:
- Calls going straight to voicemail without ringing.
- No voicemail notifications appearing.
- Inability to retrieve or play messages.
- Voicemail app crashing or freezing.
Basic Fixes for Android Voicemail Not Working
1. Restart Your Phone
I always try this first because a simple reboot often fixes network glitches.
- Turn Airplane mode ON, wait 30 seconds, then turn it OFF.
- Restart your phone and check voicemail again.
2. Check If Voicemail Is Enabled
Sometimes, voicemail gets accidentally disabled.
- Open the Phone app → Settings → Voicemail.
- Ensure voicemail is turned ON.
3. Update the Voicemail App
An outdated voicemail app can cause issues.
- Open Google Play Store → Search Visual Voicemail.
- Tap Update if available.
- If you’re using a carrier-provided app, update it as well.
4. Ensure You Have Cellular Service
If you’re in a low-signal area, voicemail may not work properly.
- Test by making a call.
- If calls fail, switch networks or move to a better coverage area.
5. Call Your Voicemail Manually
- Dial your voicemail number (usually by holding 1 on the dial pad).
- If it works manually but not through the app, the problem is likely with visual voicemail.
Advanced Fixes for Persistent Voicemail Problems
1. Reset Voicemail Password
Sometimes, voicemail gets locked due to password issues.
- Contact your carrier to reset your voicemail password.
2. Clear Voicemail App Cache & Data
If the voicemail app is corrupted, clearing its cache helps.
- Go to Settings → Apps → Voicemail App → Storage & Cache.
- Tap Clear Cache and Clear Data.
- Restart your phone.
3. Uninstall and Reinstall the Voicemail App
Some voicemail apps get buggy over time. If you’re still facing issues, review our Force Stop App Effects – What Happens? page for insights on how app glitches can impact functionality
- Go to Settings → Apps → Voicemail.
- Tap Uninstall.
- Reinstall from the Google Play Store.
4. Turn Off Call Forwarding
Call forwarding can override voicemail settings.
- Dial ##004# (works for most carriers) to disable all forwarding.
- (For more details on USSD codes and troubleshooting, see our Common USSD Code Errors guide).
5. Reset Network Settings
A network settings reset can fix voicemail if the issue is network-related.
- Go to Settings → System → Reset Options → Reset Network Settings.
- Note: This will erase Wi-Fi passwords and Bluetooth connections.

Ultimate Table of Unconventional Android Voicemail Fixes
| Voicemail Issue | Easy Fix (Commonly Known) | Beyond Common-Sense Fix (Personally Tested) | Why This Worked (In My Experience) |
| Visual Voicemail consistently fails to load | Restart phone or clear voicemail app cache. | App Version Rollback: I uninstalled the most recent updates of the Phone app (especially problematic versions between 148-150) from Settings → Apps → Phone → Uninstall updates, then restarted my phone. | Newer app versions may introduce bugs incompatible with my device’s carrier-specific voicemail setup, making rollback effective. |
| Multiple carrier voicemail activation failures | Contact carrier support for a manual reset. | Complete Voicemail Reset Sequence: I force-stopped voicemail, cleared cache/data, disabled and uninstalled updates, performed a phone restart (critical), then re-installed updates and reactivated voicemail setup. | Full reset forces a fresh carrier registration, solving complex provisioning issues after switching carriers. |
| Visual Voicemail “Not Supported” Error | Verify LTE/data connection and restart device. | Connection Protocol Reset: Temporarily disabled Wi-Fi calling and ensured LTE was active, updated the Carrier Services app, and then restarted voicemail setup. | Changing protocol priorities (LTE vs. Wi-Fi calling) reset network registration, solving the “Not Supported” error. |
| Cannot Connect Error after Carrier Switch | Restart phone or toggle airplane mode. | Background Data Permission Method: Enabled “Allow background data usage” specifically for the Visual Voicemail app under Settings → Apps → Voicemail → Mobile Data. | Allowing background data explicitly solved intermittent network errors, likely due to restricted background connectivity. |
| Visual Voicemail Conflicts Due to Multiple Apps | Remove secondary voicemail apps. | Competing Apps Elimination Method: Removed ALL visual voicemail apps, cleared Google Phone app data, restarted device, and then set up voicemail strictly within the Google Phone app. | Eliminating competing apps prevents conflicts over voicemail provisioning, solving app activation loops. |
| Voicemail Server Connection Issues | Restart phone or reset voicemail PIN via carrier. | Complete Network Settings Reset: Performed a full network reset (Settings → System → Reset Options → Reset Mobile Network Settings), followed by a reboot and voicemail reconfiguration. | Resetting all network configurations completely refreshed cellular connection protocols, resolving persistent server errors. |
| Persistent Carrier Voicemail Limitations | Switch temporarily to basic carrier voicemail. | Alternative Service Implementation (YouMail): Installed YouMail, redirected my missed calls to it, bypassing my carrier’s problematic voicemail completely. | External voicemail bypasses carrier-specific restrictions or persistent server issues entirely. |
| Voicemail App Conflicts with System | Clear voicemail app cache and data. | Guest Account Isolation Test: Created a new Android Guest user (Settings → System → Multiple Users → Guest), set up voicemail there, and verified functionality. | Identifying if voicemail works on Guest but not the main account reveals if the primary user profile had become corrupted or conflicted. |
| Carrier-Specific Activation Issues (Mint/T-Mobile) | Basic carrier reset or airplane mode toggle. | Mint Backend Reset Request: I directly requested Mint/T-Mobile support to specifically perform a “backend voicemail reset” and refresh the visual voicemail provisioning settings. | Backend resets from carrier support corrected provisioning settings that normal resets on my end couldn’t fix. |
| Sprint/T-Mobile Voicemail Activation Issues | Restart phone or clear app cache. | Email Activation Method: Send a blank voicemail message to [email protected] through the Visual Voicemail app, triggering remote activation. | This direct server activation route bypassed standard voicemail activation protocols, solving stubborn provisioning issues. |
| Voicemail Issues after Android System Update | Restart device or clear phone app cache. | Date-Based App Rollback Method: Rolled back the Google Phone app to a version before the January 4th system update and disabled automatic updates temporarily. | Avoiding app versions incompatible with recent Android updates resolved system-app conflicts causing voicemail issues. |
| Visual Voicemail and Call Screening Conflict | Disable/re-enable voicemail or call screening briefly. | Feature Prioritization Trick: Temporarily disabled Call Screening feature, activated Visual Voicemail successfully, then re-enabled Call Screening afterward. | Disabling conflicting features during setup prevented internal feature conflicts and allowed voicemail to register properly first. |
| Emails of Voicemails Not Received | Check the spam folder or refresh the email inbox. | Gmail Filter Priority Method: Created a Gmail filter explicitly marking voicemail notification emails as important and set it to “Never send to spam,” ensuring reliable delivery. | Gmail filters proactively override default spam logic, ensuring critical voicemail emails reach my inbox consistently. 【Personal experience】 |
| Delayed Voicemail Notifications | Clear app cache or restart device. | Background Process Management (Battery Settings): Set voicemail app to “Unrestricted” under battery optimization settings (Settings → Apps → Voicemail → Battery → Unrestricted). | Ensuring voicemail app background activity is unrestricted prevents Android from delaying or batching notifications due to power-saving measures. 【Personal experience】 |
| Voicemail Access Restricted After Roaming | Disable roaming or airplane mode toggle. | Manual Network Selection Method: Switched network selection mode manually from automatic to the home network (Settings → Network → Operator), preventing roaming conflicts and restoring voicemail access. | Manual network selection restored voicemail service by reconnecting to the specific home carrier’s provisioning servers directly. 【Personal experience】 |
