> A mobile failover would be cheaper and would give you better connectivity in heavy rain.

When I was living in the rural seaside (literally grapes growing in front of the sea: nice place), when a bad electricity outage would happen it'd take down everything, including the only cell tower we'd be connected to. So no Internet, no mobile phone. No nothing but the laptop's batteries.

There are also people who have the same ISP as the company giving them their phone number: about a year ago in my country (highly modern, western EU country) a major carrier went down for a few hours. Electricity kept working but all the people on that ISP and mobile phone carrier were sorry out of luck. Most shops couldn't accept payments anymore (except cash but people don't use that much here).

Failover on mobile is, for many, the same thing as no failover at all: you may as well not even bother.

Satellite failover, on the other hand, is quite harder to disrupt.
