Simulsays is a WM application, and simulscribe service replaces your normal ATT voicemail. When someone leaves a message, it is sent to your phone, and you can see it - much like iPhone visual voicemail. So you can look ant and review the voice mail in any order you want, or just delete it. But what makes it even better is this.

It is transcribed, so you can READ it, and you can play back the audio recording of the message which is also delivered to your phone.
