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

Care to point me to it? The best I can find searching a bit with unlimited data is capped to 64 kbps for $100/yr, which is quite a bit worse.

I haven't checked, but see what good2gomobile.com offer on their plans if you pay for a year. I'm on the $5/mo plan for my primary cellphone.

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.

For security applications where most of the image doesn't change, 500 Kbps is fine for low resolution video streaming.
