Thought I'd post this before Mole does.

"Starlink, which already has 87,000 subscribers to home broadband in Britain, could seek to launch a “virtual” network using existing phone networks but augmented by its satellites"
I'm not sure if the article is suggesting that Satellite providers, like Starlink, will start their own MVNO's in conjunction with some sort of add on satellite functionality, but that would be more of a threat to other MVNO's rather than the MNO's that own the mobile networks
This article talks about Direct to Phone (Mobile) service as if it's an easy thing to achieve with enough satellites in orbit, in my opinion it's anything but easy. Mobile phones aren't particularly directional, so the satellite would have to use it's phase array directional antennas to provide the gain to hold up the call's, so if you're providing simultaneous service to multiple devices each device would need to use a significant portion of the satellite antenna array. Because most LEO's orbit at an altitude of around 500Km, travelling at around 28,000Km/hr, how many handoff's and individual mobile's will each satellite be able to handle in a particular location? To service more mobiles, you need higher Frequencies with larger bandwidths, but the higher the Frequency the more you suffer from atmospheric affects.
I can see how they might be able to deal with one or two calls in the middle of nowhere, but direct to mobile isn't a threat to terrestrial MNO's. A more sensible approach is to have remote 5G cells that uplink to LEO's, providing a backbone service for localised mobile devices. An alternative to LEO's, that would work directly with mobile, are High Altitude Platforms (HAP's).
