The "free" Starlink service is calling 911. It is expected that mobile provider offers 911 service to everyone.
Starlink, in partnership with T-Mobile and others, will be offering service with messages and voice but no data. I don't think pricing has been announced, or if going to be add-on or free extra. My guess is that it will be cheap cause it isn't much demand, the emergency is the important part.
Also, there are multiple companies working on LTE from satellites. They are at disadvantage cause can't piggyback on lots of low satellite. But might be able to work with fewer, higher satellite. They might be able to partner with other providers.
