You can use any other line to call yourself and listen your VM. Call your phone number. When you hear your voicemail greeting, press the star key (*) and then Enter your voicemail password
Instead of find another phone to call, what many people do is to use VoIP app to make the call. Download free VoIP app like TextNow. It will give you a new 10 number and you can call any US and Canadian numbers for free using the app. The app will work as long as you have Wifi or Mobile data. Using that, you call yourself and listen to the VM
