I connected and configured a SIM card to my BlackVue DR750-2CH LTE, and I can connect to it occasionally using the smartphone app when the WiFi is off, so I suppose that the SIM card is functioning properly. But I keep getting a Disconnected then Connected notification to my phone very frequently:
I have FW version 3.19 (Release date: 2021-05-24)
This makes the cam pretty useless to me because the only reason I bought it is LTE in parking mode. Please assist.
I see that there are a few more posts about this from previous years: 1, 2, 3, but I don't see a solution in those threads.
