I loved this application ... until Saturday.

Somehow, the application logged itself off from the Simulsays network and, as a result, I missed three messages. If the phone had been turned on, then at least I would have received a missed call notification, but I was at the beach and the phone was in my car, powered off. When I powered the phone on, the Simulsays app didn't connect and I didn't get the messages until a day and half later when I figured out that the app hadn't connected.

It doesn't makes sense for me to take a chance at missing messages like this, especially when I'm frequently in areas with no coverage (on the subway, in elevators, etc.) and I wouldn't even know I had missed a call.
