The "85% of their bandwidth" part is super interesting. It implies usage for much more than occasional emergencies. Globalstar has ~12Mhz of global S-Band spectrum[0], which they describe as "3.7 Billion MHz-POP", a unit I'm not grokking.
But I am pretty sure that is a LOT more bandwidth than what will be used for highly compressed text messages in emergencies.
