Look for an update of carrier settings

There aren’t many people who are aware of this, but occasionally your carrier settings need to be updated. Even while it doesn’t happen frequently, when it does, it means that refreshing can often fix carrier issues. This recalls when you didn’t receive voicemails on your iPhone.

Fortunately, updating your carrier’s settings is simple. Your carrier settings can be viewed by going to Settings > General > About. You can even install carrier update if it is asking for it. If not, all you’ll see is your carrier information.

Your iPhone needs a cell network association for voice messages to function. Look at the screen of your device in the upper left corner; there may be a No Service error there. This suggests that you are currently not connected to your carrier. This might be a sim-card issue, as expected.

  • Get rid of your SIM card.
  • Blow its opening and slot (Residue may have entered them, preventing the proper scanning of your SIM.)
  • Replacing the SIM
  • Additionally, it’s possible that your remote carrier is managing outages and that’s why you’re experiencing the No Service error.

Restart the cellular network after turning it off.

A quick reset of your mobile cellular data might occasionally resolve some problems. In the unlikely event that your audio messages aren’t uploading rapidly enough, this is evident. Receiving notification of a missed call after hours is a good indication.

You can accomplish this by turning your phone’s cellular data on and off repeatedly or by setting it to airplane mode.

You can do this by frequently turning on and off your phone or by switching it to offline mode. Call your phone from a separate device after doing so to see if your voicemail is now working or not. If you get a voicemail after performing the above steps, then the issue is resolved.

Verify cellular data is turned on

In general, cellular data is crucial for receiving phone texts. Considering that voice messages are a feature of carriers, interacting with information ensures that your voice messages are delivered. Cellular data is also important for the Visual Voicemail feature to work. Without cellular data being switched on you cannot perform any task. You can listen to a voicemail without paying attention to it at this point.

Turning on your voice message could help you identify the issue if it’s not working and you don’t have information switched on. To enable it, go to Settings > Cellular and select Cellular Data. If you have a data plan with a limited data allowance, there are ways to utilize less data while still receiving phone calls.

Activate Wi-Fi Calling

Voicemails take up your Wi-Fi to get downloaded to your device if you live in an area with a bad connection. Bad connections may also cause missed call notifications to appear on your phone without your phone ringing.

If this happens to you, you may check by turning on your device’s Wi-Fi. Additionally, it helps you receive better sound quality and reduces missed calls.

Ensure that Call forwarding is turned off

Your calls will be sent to a different number if you have Call Forwarding activated. While normally disabled, it occasionally has the potential to become enabled accidentally if you’re fiddling with the settings. You aren’t getting phone messages as a result, if it is enabled.

Go to Settings > Phone > Call Forwarding and tap Disable to disable it. Call forwarding may not be enabled on all carriers.

Reset Network Configuration

It’s possible that resetting the network settings will help if your iPhone’s voice message still doesn’t function following the previous repairs. This also helps if you have other reasons such as missed calls that don’t ring on your phone or problems with mobile data.

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings to clear the network settings.

Use the Conventional Method to Access Your Voicemail

Although Visual Voicemail and the phone app are ideal, they are by no means the only ways to check your phone message in the case that they aren’t working. If after trying the aforementioned methods your iPhone’s phone message still doesn’t function, you may need to check your voicemail as it was done back in the day. You can check your phone message through your carrier by dialing your number on your phone.

The final four digits of your phone number are typically the default secret word, just in case you don’t know it.

Verify that voicemail is set up

Perhaps you didn’t put up a visual phone message. Many people believe that iPhones automatically have the element enabled, but you need to do so.

If you assume that an iPhone phone message is in progress, there is a quick way to check:

  • If you haven’t set it up, do the following:
  • Launch the Phone app.
  • Locate the Voicemail tab, then click on it.
  • select setup
  • Enter a four-digit or six-digit passcode.
  • Click Done

If you need to use a default or custom hello, you’ll be informed when you click “done.” There are many options to look through if you choose the default route.

However, if you’re having problems, you can get in touch with the company that provided your remote setup. Your interaction with the company will be guided by their customer service team.

Update iOS

Try refreshing your iOS, if you are using an older version to fix the issue. You can be one of the uncommon people who refuses to install fresh firmware because they genuinely detest the way the new upgrades appear.

  • To update the software, go to Settings > General.
  • Click update.

  • General > Settings > Software update
  • Set automatic updates to on
