We have devices sending telemetry and occasional OTA updates without urgency (if it takes a few hours to get it over it’s not a problem).

If you need consistent MB range traffic for cameras I wouldn’t advise it but for low (5kbs) traffic it can be attractive. A few thousand bits can encode quite a bit of information. Don’t be fooled by the “kbs”.

You can do quite a lot with a few MB. Don't tell every React behemoth on the web that we know this trick.
