How should a user verify if their visual voicemail is working?

To verify if visual voicemail is functioning properly, a user should check settings in the voicemail app. This option is the most relevant because visual voicemail is a feature that can be directly assessed within the settings of the voicemail application itself. Within the app, users can see if their voicemails are being received and accessed correctly, as well as review configurations that enable visual voicemail, including the setup of their voicemail box.

Using alternative methods like dialing their phone number or texting the voicemail box may not provide a clear assessment of whether visual voicemail as a feature is operational. Dialing the phone number might lead to hearing voicemail messages but won't confirm if the visual voicemail interface is functioning as intended. Similarly, sending a text to the voicemail box doesn't pertain to checking the operational status of visual voicemail features. Therefore, checking the voicemail app settings is the most straightforward and effective method to ensure that visual voicemail is working properly.
