    The most impressive part is that the satellite is able to receive the phone’s signal. I’m really surprised by that.

    Phones receiving satellite signals is nothing new, GPS works like that, but two way communication is much harder since phones are much less powerful.

    I guess it has to do with how large the antennae are.
