Hourly data collection for science like stream gages, earthquakes, air quality, precipitation, or similar in very remote areas.

Sensors along a pipeline etc to monitor remote infrastructure.

Texting in remote areas for logging, cattle, forestry services, etc.

Redundancy for boats, emergency services etc that may have primary and secondary communication channels, but still greatly benefit from the capacity for redundant txt messages.

Wouldn't a pipeline be ideal for a wire or fiber just by attaching it along it?

A wire like that is a single point of failure. Great for sending lots of data, but using two different systems is safer than using two different wires along the pipe, both of which could be severed in the same event.
