TIL standby mode. Is that enough to operate a remote webcam? Not real time video feed but say uploading a photo every 1 minute or so
Apparently you get unlimited data capped at 500 kbit/s. So that would be a clear "yes".
You can find something similar with IOT sims. And then you just need a standard 4g/5g dongle/router
Depending on a whole bunch of things but a 200KB photo once a minute might be in the realms of LoRa. You could get the data out for free.
The 500Kbps of Starlink would be close enough for a 500KB photo every 10 seconds or so assuming typical packet overheads.
