So I have my blackvue 900x connected to my lte module. When I push the sim card icon it gives me a message retrieving sim card info, then after 20 seconds goes back to a message please connect lte module to activate sim card? It's still connected to the camera. The sim card is new from at&t and active. Not sure if it activated in setup. But to acess that it has to connect to the plugged in sim card. Thanks for any help with this. Dave
