It works great on the M8, I think much better than how it works on Android. On Android it installs an app, you have to use that app in order to send and receive messages in order to get the benefit of VZ messages. On the M8, it integrates into the OE messaging app, runs behind the scene synchronizing your messages and it's available in the Store from Verizon for download, I love it. But on my Icon, I can't find the app in the Store, I don't understand why since they are both Windows Phones on Verizon.
