Starlink service will not compete with cell phones; the terminals are too large. If anything, it will complement cell service, by making tower backhaul easier.

Starlink service will not compete with cell phones; the terminals are too large. If anything, it will complement cell service, by making tower backhaul easier. It's also unlikely to directly compete with wired ISPs in cities, as the bandwidth required for everyone to have a terminal would be high. But it could enable unwired 5G stations as micro-ISPs, which would be a similar effect. What it will kill are rural or undeveloped area ISPs (such as they are) and provide high threat to undersea cables and cross-country fiber.
