It's actually a federal law that cell phone companies have to pass-through 911 calls in the US even if service is not active. That is one reason your phone will say "SOS" when it can't reach your particular cell provider -- when "SOS" appears, it means it can reach another provider that will let your dial 911.I’m sure there’s been situations this year where people haven’t been able to contact emergency services via their phones because they failed to pay their cellular phone bill. I don’t think there’s been any impact to those companies.![]()
This, by the way, is not true with Satellite services. For example, if you have a Garmin Inreach, and discontinue service, you cannot reach emergency services.
