So my father bought a 900X Plus and the SIM card module for cloud connectivity and we are just having a beast of a time getting it all working. The camera's already installed with the latest firmware, connected to the SIM module, WiFi active, etc. When I go through the setup on my iPhone for the SIM card it takes a few minutes and either times out or the APN for AT&T LTE (USA) is 'incorrect' and doesn't seem to show the IMEI consistently in the iPhone app no matter what we do. We've tried 2 SIM cards, one activated already with an old iPad I had laying around that I no longer use and a freshly activated (from the AT&T store) SIM card. My father managed to 'get it working' but I suspect he's confusing WiFi connectivity with LTE and he's getting into situations where he thinks LTE is working but only because his phone is in the car and the camera happens to be using it as a hot spot instead of the module. I'm at a loss on what the next steps are, do we just start over from scratch and 'reset' the camera back to factory defaults and start over. Do I maybe use his android phone and blackvue app instead? The camera's added to his account and he's logged into it, just don't want to use the SIM module.
