Premature and very dangerous move, the public is at great risk, only
Sat phones seem to work when there is a natural disaster. Cell phones
for the most part can't even connect to 911....

tohoku quake
 o land voice phones did not work
 o mobile phone voice did not work
 o mobile phone text did not work
 o land ip worked, adsl, ftth, ...
 o mobile phone data worked!

you could send email but not make a voice call

How will you exactly "connect to internet" during such massive downtime? I
mean mobile data is dead, and with dead landline I assume cable broken -
then how exactly one can send email? :)

perhaps you should read a bit more carefully.  mobile data was not dead,
mobile voice was.  land voice was dead, land data was not.
