Once more, please try later Problems with your SIM card or your phone’s operating system are the most common causes of Voicemail errors. There have been reports of this problem on both iOS and Android devices.
Also, it is not tied to any one network operator like T-Mobile, US Cellular, etc. The following are examples of common error messages that a user may see:
Method 1: After The Phone Has Been Restarted, Reinsert The SIM Card.
The discussed voicemail issue may be the result of a temporary communication malfunction between the user’s device and the voicemail modules of the mobile carrier. Here, removing and reinstalling the SIM card after restarting the phone could solve the problem.
To clarify, let’s use an iPhone as an example. Verify with the user’s mobile service provider that voicemail has been enabled for their account.
Step 1: To increase the iPhone’s volume, press and hold the button down for a few seconds.
Step 2: Please swiftly push the iPhone’s volume down button and then release it.
Step 3: Then, you need to unlock your iPhone by pressing and holding the lock button.
Step 4: Once you’re ready to use your iPhone again, press the lock button once again to unlock it, and then press the power button.
Step 5: Now see if the voicemail issue still exists on the iPhone.
Step 6: In that case, turn off the iPhone and take out the SIM card.
Step 7: Turn on your iPhone, but don’t insert your SIM card just yet.
Step 8: Turn off the iPhone and re-insert the SIM card.
Step 9: Put the iPhone back together and listen to the voicemail to make sure it’s functioning properly.
Method 2: Make Sure You Have the Most Recent Phone OS Version
This issue may occur if the phone’s operating system is not compatible with the mobile carrier, preventing the carrier from accessing the necessary voicemail modules on the phone.
Here, upgrading the phone’s operating system to the most recent build could solve the voicemail problem. As an example, we’ll go over how to install a new version of iOS on an iPhone.
Step 1: It is recommended to fully charge the iPhone and then connect it to a Wi-Fi network in order to avoid any interruptions in the iOS upgrade process due to a slow or unreliable mobile network.
Step 2: Then, go to your iPhone’s Settings > General menu.
Step 3: Select Software Update now, and if an iOS update is available, let it download and install itself.
Step 4: After updating to the most recent version of iOS, reboot the device and see whether the voicemail issue still persists.
Method 3: Delete Voicemail App’s Cache and Data
Since the critical voicemail modules are unable to run if the cache and data of the voicemail app are incorrect, this particular voicemail issue may be encountered by a user.
In this case, deleting the voicemail app’s temporary files and cache could fix the issue. We’ll use the T-Mobile Visual Voicemail app for Android as an example device.
Step 1: Initiate the Apps and Settings menu on your Android device.
Step 2: Activate the Force Stop option in T-Visual Mobile’s Voicemail.
Step 3: The next step is to verify that you want to terminate Visual Voicemail in this way, and then open Storage.
Step 4: First, select “Clear Cache,” then “Clear Data,” and finally “Clear Storage.”
Step 5: After doing so, verify that you want to clear the Visual Voicemail app’s data, and then see if the voicemail error has been fixed.
Step 6: Whether it doesn’t work, try switching to the stock voicemail app and seeing if the problem persists.
