The only problem with the new feature is that it won't work unless carriers support it, and for now, the only two that do are T-Mobile and Orange in France. Hollis also mentioned that "voicemail will not load on WiFi. Only on mobile data," so you won't get the service unless you have a cell signal. The support ticket revealed native voicemail-to-text transcriptions as well, but it'll reportedly require carrier support, and none are doing so for now. That said, the app is still in a basic state, and features like transcription may be available when Android M arrives in the fall.
