It sounds like the data rate is incredibly low. That allows for a lot of signal margin. GPS receivers are sensitive to something like -165dBm. It's probably harder for the satellite to hear from the phone. Especially at a lower frequency like 700Mhz, a phone's tiny antenna is going to be a rather inefficient transmitter. Maybe 5g technology helps by allowing the phone to do some rudimentary beam forming using multipl…

(How) Does beamforming work in a moving device?

I think the "complicated antenna requirements" still exist - they've just put the complicated antenna on the satellite, instead of on the phone.

Yeah that's not how it works. You can't just "put the complicated antenna on the satellite, instead of on the phone" and declare this problem solved. If you believe that I have a bridge to sell you. I'm declaring shenanigans right now on Elon's pitch but what else is new. It makes me sad that this thread is full of (probably) SWEs in a complete froth who took this at face value with little understanding of how antenn…

"T-Mobile users will be able to use messaging, MMS and certain messaging apps, from remote points across the lower 48 states, Alaska, Puerto Rico and Hawaii and even some remote points in the water.

"I would expect our pricing for this service to be the un-carrier's favorite price: we expect, on our most popular plans, for this service to be included for free" https://youtu.be/Qzli-Ww26Qs?t=851

Yes, that's what I said. Edit: Downvotes are happening for some reason. "most likely" and "I would expect" mean basically the same thing unless we're playing grammar police. The entire point of my above post was to deny the fact that they "did not disclose specific pricing". That was the part that was incorrect that I was correcting, as shown in the long form direct quote.

Let me clarify. Musk claimed 6 years ago [1] that shipping Teslas would be capable of Level 5 autonomy. While Tesla’s markets their feature as “full self driving” it’s a far cry from even level 3 afaik. It’s kind of sad people fall for this. It also has lethal consequences as people assume it can do things it very well can’t (cruise control+ is really what the feature is). It’s a very obvious grift and SEC and FTC re…

Musk already admitted that he was very wrong about FSD and that it's not that easy. Sure his talk was dumb and a lot of people fell for it, but that's just how marketing works.
