語音郵件不在Android上

首先確認運營商是否已啟用語音信箱，可從其他電話撥打自己的號碼測試，若未轉接至語音信箱，需聯繫運營商激活；2. 檢查手機設置中的語音信箱號碼是否正確，不同運營商對應不同號碼（如Verizon為*86或本機號碼，T-Mobile和AT&T通常為*86）；3. 在電話應用中嘗試關閉並重新啟用語音信箱功能，重新輸入號碼並設置問候語；4. 確保Carrier Services和SIM Toolkit應用已更新，檢查系統更新以獲取運營商設置修復；5. 清除電話應用和語音信箱應用的緩存數據以解決臨時故障；6. 重啟手機前重新插拔或更換SIM卡以排除硬件接觸不良或損壞問題；7. 安裝其他語音信箱應用（如Google Voice或運營商官方應用）測試功能是否恢復；8. 重置APN設置為默認值以修復網絡配置錯誤，避免影響語音服務；若以上步驟無效，聯繫運營商確認賬戶狀態或線路問題，必要時請求重新配置語音信箱服務，大多數問題無需恢復出廠設置即可解決。

Voicemail not working on Android is a common issue that can stem from various causes — carrier settings, app glitches, network problems, or incorrect configurations. While frustrating, most cases can be resolved with a few troubleshooting steps. Here's what to check and do.

1. Check Carrier Voicemail Setup

First, confirm that your carrier has voicemail properly set up for your line. Some carriers require you to activate voicemail manually the first time.

• Call your own number from another phone and see if it goes to voicemail after a few rings.
• If it rings indefinitely or disconnects, voicemail may not be enabled.
• Contact your carrier's customer service or visit their support site to activate or reset voicemail.

Many carriers also have a dedicated voicemail access number or a default voicemail number you can call (often by holding down the "1" key). Make sure this is correctly configured.

2. Verify Voicemail Number in Settings

An incorrect voicemail number is a frequent cause of the issue.

• Go to Phone app > Settings > Voicemail (path may vary by device and carrier).
• Look for Voicemail number and ensure it matches your carrier's required format.
  • For example:
    • Verizon: Usually your own number or *86
    • T-Mobile: *86 or your number
    • AT&T: *86 or their specific access number
• If unsure, contact your carrier for the correct number.

On some Samsung phones, you may need to go into Call settings > More settings > Voicemail to adjust this.

3. Reset Voicemail in the Phone App

If the number is correct but voicemail still isn't working, try resetting it.

• Open the Phone/Dialer app .
• Tap the three-dot menu > Settings > Voicemail .
• Disable and re-enable voicemail.
• Re-enter your voicemail number and try calling it manually to set up the greeting.

Sometimes just reinitializing the voicemail link prompts the setup process again.

4. Check for Carrier Services and Carrier Settings Updates

Outdated carrier settings can break voicemail functionality.

• Go to Settings > Apps > Show system apps .
• Find Carrier Services and SIM Toolkit , ensure they are updated and not disabled.
• Also check for a Carrier Settings update:
  • Settings > About phone > Software update > Check for updates (some carriers push voicemail fixes this way).

Updating your device's software can also resolve underlying bugs affecting voicemail.

5. Clear Cache of Phone and Voicemail Apps

Corrupted cache data can prevent the voicemail feature from working.

• Go to Settings > Apps > Phone app (might be called "Phone," "Dialer," or your manufacturer's name like "One UI Dialer").
• Tap Storage > Clear Cache (do not clear data unless necessary).
• Repeat for any Visual Voicemail app listed separately.

This often resolves temporary glitches without affecting your call log or settings.

6. Reinsert or Replace SIM Card

A faulty or loose SIM can disrupt network services, including voicemail.

• Power off your phone.
• Remove the SIM card and inspect it for damage.
• Clean if needed, reinsert firmly, then restart the phone.
• Wait a few minutes for the network to re-register.

If you have access to a spare SIM (especially from the same carrier), try swapping to test.

7. Test with a Different Voicemail App

Some Android phones use third-party or carrier-specific visual voicemail apps that may malfunction.

• Try downloading a different dialer app (eg, Google Voice, My Verizon, T-Mobile Visual Voicemail ) from the Play Store.
• Set it as default and see if voicemail works there.
• Google Voice can even act as a workaround by routing voicemails through its system.

If it works in another app, the issue is likely with your default phone app or its integration.

8. Network and APN Settings

Incorrect APN (Access Point Name) settings can interfere with voice services.

• Go to Settings > Network & Internet > Mobile network > Advanced > Access Point Names .
• Tap the three-dot menu and select Reset to default .
• Restart the phone afterward.

Only modify APN settings if you know what you're doing — incorrect changes can break data or calling.

If none of the above works, contact your carrier to verify there's no account-level issue or outage in your area. Sometimes, resetting your line or re-provisioning voicemail from their end is the only fix.

Basically, start simple — check the voicemail number and try calling your own phone — then work through settings and carrier support. Most issues aren't permanent and can be resolved without a factory reset.
