Service Provider Voicemail

It sounds like a voicemail notification from your service provider might have been received as a missed call, causing the entry to show up in your voicemail screen. Sometimes, when a call is missed, especially from service providers or systems like Voicemail, it leaves an entry in your voicemail log.

To remove it or clear the notification, you can try the following steps on your iPhone XR:

1. Sometimes, a simple restart can resolve minor glitches or clear out notifications.
2. Go to the Phone app, then tap on the Voicemail tab at the bottom right. Check for any unheard or unopened messages. Listen to or delete any messages present.
3. If you're not able to access the voicemail or if there's any issue with it, you might want to reset your voicemail password through your service provider's website or by contacting their customer support.
4. Go to the Voicemail tab, swipe left on the "Service Provider Voicemail" entry, and tap the "Clear" or "Delete" option to remove the notification.
5. If none of the above steps work, it might be beneficial to contact your service provider directly. They can assist in checking if there's any issue with your voicemail or if there's something specific causing this notification.

Remember, the terminology and options might slightly differ based on the carrier or iOS updates, so if you're having trouble, contacting your service provider or checking the Apple support page for your specific iOS version could provide more accurate guidance.

Please contact your Carrier as VoiceMail is a carrier-specific feature --> Check your voicemail on iPhone - Apple Support

VoiceMail, whether it's visual voicemail or the traditional voicemail service, is a carrier-specific feature that depends on your cellular service provider. If you are experiencing any issues related to voicemail on your iPhone, it's essential to get in touch with your carrier for assistance. Here's how you can check your voicemail on an iPhone and what steps you should take if you encounter any problems:

Checking Voicemail on iPhone:

1. Visual Voicemail: On most iPhones and carriers that support visual voicemail, you can access your voicemail messages directly from the Phone app. Open the Phone app, and you should see a "Voicemail" tab at the bottom. Tap on it to access your voicemail messages in a visual and user-friendly interface.
2. Traditional Voicemail: If your carrier doesn't offer visual voicemail or if you prefer the traditional voicemail service, you can access your voicemail by dialing your carrier's voicemail number from your iPhone.

Troubleshooting Voicemail Issues:

1. Voicemail Not Working: If you are experiencing issues with accessing or receiving voicemail messages, it's essential to contact your carrier's customer support. They can help you troubleshoot the problem and ensure that your voicemail service is set up correctly.
2. eSIM Users: If your iPhone uses an eSIM, ensure that the eSIM is activated and set up correctly with your carrier. Any issues with the eSIM activation can affect voicemail functionality.
3. Network and Coverage: Sometimes, voicemail issues may be related to network coverage or signal strength. Check that your device has a stable cellular connection.

The error message "Voicemail error performing request unknown iPhone" typically indicates an issue with the voicemail feature on your iPhone. There are several potential reasons for this error, and here are some troubleshooting steps you can follow to resolve the problem:

1. Ensure that your iPhone has a stable internet or cellular connection. Voicemail services may require a data connection to function correctly.
2. Check if there are any carrier settings updates available for your iPhone. Carrier updates can sometimes resolve voicemail-related issues.
3. Contact your carrier's customer support to ensure there are no known issues with their voicemail services in your area.
4. If you have call forwarding enabled, try disabling it to see if it resolves the voicemail problem. Go to "Settings" > "Phone" > "Call Forwarding" and turn it off if it's enabled.
5. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.

6. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.

   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
7. Make sure you have the latest updates installed.

   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
