I can tell you this, when you set it up for cell phone connection you have to turn off the wifi in the smart phone to test. It doesn't matter if the only profile in the ST500 is setup for cell connection, WiFi in the phone has to be off. I am in the process of working with a customers IT tech involving a watchguard router and it's not going well, I can connect on the local WiFi but not over the cell.
