On my device I've disabled SMS push but I left Enable Push and Use Network Push enabled. On GMS server network push is enabled and there is correct server name entered in the network push server name dialog box in the admin console. Every time after I send a test email to myself, the screen on the phone comes on approximately 30 - 40 seconds upon receiving the message in GroupWise. However, I don't get new mail notification on the phone (yes, notifications are enabled) nor the message is being downloaded to the phone.
