There's also Viasat/Inmarsat but as they are primarily GEO, I think they rely on partners for adding LEO. And as Dan is explaining, there are many possible partners.

@joerg: \"Starlink is beyond many people's reach (economically) in many countries\" . Well, sure, but often there is no alternative, as deployment of 3GPP towers even with radio links is often not considered whenever the density is not enough. So at least they have one alternative now where in many places there was none.

Starlink IS expensive in many countries... but I think it will be interesting to see what Amazon Leo will do on pricing. Amazon is good at making consumer equipment inexpensively (decreasing startup fees) ... and could afford to offer lower costs subscriptions.

I have a rural house, where my only option was a WiFi link to a tower, which had a WiFi link to a tower, which had a WiFi link to a tower, which had a WiFi link to a tower which had a T3 to the Internet (in 2024). At night I would get ~12kbps to the Internet.

Couldn't agree more -- but your monthly salary is probably substantially higher than the Starlink subscription fee per month. This doesn't hold in many places. Not talking about the developed world

rather than payinx 2 starlink subscriptions, you better get one subscription from two providers for bonding, apparently it will work better.
