Agree with the post from June 29
This app has lots of great potential. For example, I love the fact that you get a transcript of voicemail messages if you miss a call. However, connectivity is always an issues. Very often, it is difficult to place and receive calls, even via WiFi. Also, the call gets dropped anytime there is a transition from WiFi (indoors) to cell data (after stepping out of a building). If the connection issues could be worked out, this would be a five-star app.
