That should let you see whether it's receiving the voicemail sms notifications at all, and possibly whether the apps are ignoring or deleting them. I've not tried it myself.
There's an open improvement request related to the Visual Voicemail signalling for ModemManager.

That is a very usefully trick, I tested it and did not see anything come in after I left the voicemail but I am not sure because after the call a ton of code happens that I can not make heads or tails of, do you know what specifically I am looking for?
