1. Check Down Detector for a Service Outage

One reason your T-Mobile voicemail may not be working is because of a service outage.

Therefore, check a site like Down Detector to see if there’s a T-Mobile outage in your area.

However, when there is an outage with T-Mobile services, there’s nothing you can do except wait for T-Mobile to fix the issue. Note that this can take anywhere from 2 to 24 hours.

2. Restart Your Device

Regardless of what your issue is, one of the best fixes for smartphones and other tech products is to restart your device.

Furthermore, restarting your phone can fix memory issues or glitches, which may be causing you to experience your voicemail to glitch out.

3. Move to an Area With Better Signal

If your T-Mobile phone has less than two signal bars, your service may be unreliable and you may not have enough signal to access your voicemail.

Therefore, if you want to fix your T-Mobile voicemail, try to move to an area with a better signal and see if four bars allow you to access it.

4. Update Your Voicemail App

If you’re using the T-Mobile Visual Voicemail app, you may want to update it to see if that fixes the issue.

Also, it’s easy to update the Visual Voicemail app by opening the app store on your device and checking if an update is available for Visual Voicemail.

If there is an update, then download and install the update and try to access your voicemail again with the updated version.

5. Disable Battery Saver

5. Disable Battery Saver T-Mobile

You may have a battery saver or power saver mode on your device enabled, which could cause your T-Mobile voicemail to not work properly.

Therefore, disable the battery saver or power saver mode and see if that fixes the issue.

6. Update Your Operating System

Performing an operating system update can help fix issues with your phone, like if your voicemail isn’t working, so go into “Settings” and see if there is a system update available.

Additionally, download the system update and your phone will restart at least once during the installation of the update, and then try to load your voicemail again.

If you’ve noticed your voicemail isn’t working, you can try to delete the app and reinstall it if you’re using Visual Voicemail.

8. Try Calling Voicemail From a Non-T-Mobile Phone

You can try to dial 1-805-637-7243 from a non-T-Mobile phone, such as a landline, and see if you can access voicemail that way, since sometimes it’ll work from a different phone.

9. Clear App Data & Cache

You can go into your “Settings” and then go into “Apps” to find your voicemail app and click on it to clear out the app data and cache.

Also, it’s a good idea to clear out app data and cache anytime you’ve noticed the app is slow or isn’t working properly.

10. Restart Voicemail App

You can try to restart the app to see if that fixes the issue.

Then, go to your voicemail app on your device and open it again, which may resolve the problem.
