I wonder what the user experience was like. Did they have to select "Starlink" instead of "T-Mobile"?

If not, was there some kind TMobile-signed-starlink's-key situation?

It's an interesting interplay between preferring user consent versus wanting things to just start working when they need to.

This is for where there is no T-mobile coverage, so there is no need to choose satellite over a terrestrial station.

Roaming is generally automatic with no "consent" involved.

Your phone provider definitely has to have a roaming agreement. Without that, your phone won’t attach to any 3G network and beyond (3G introduced mutual authentication).

GSM remains vulnerable to all kinds of bad things since it only authenticates the phone/SIM to the network but not otherwise).

True. This vid was a major eye opener for how insecure the current staus quo is:

In the limit, security is opposed to everything that's good and nice, safety included.
