Doesn't it use regular cellular frequencies? You might be able to "disable this" by using manual network selection, but if they use the same mcc mnc as tmobile (their partner), it'll be impossible to distinguish.

Its only intended for emergencies...

So by all means, if you rather not be able to text someone that you're in the middle of nowhere in danger with otherwise no signal, I don't see why you would disable that. Like its literally for SOS use.

Probably (I've read that there will be a switch in the carrier settings for T-Mobile USA), but also why would you want to?

In the end, the Starlink satellites will be just another set of cell towers, just with a slightly unusual velocity and altitude. You already can't e.g. disable using T-Mobile base stations leased by a particular land or infrastructure owner.

Don’t use T-Mobile for now.
