There are some places in the US where the only reason they aren’t still stuck on dialup is because of the cellular data network and/or starlink sattelite internet.

Especially at the time it could have been useful as a backup connection. Where I work our network team had to work very hard to get all of our locations a backup connection that didn’t go through the same physical “line” as what we already had (so much of the physical infrastructure is comingled).
