I think it should be like Taxi's, to become a Taxi driver you have to maintain certain standards and offer a 24 hour service because of the nature of their business. There were penalties and your license could be revoked if you broke these rules.
I believe Telco's should have to have a similar laws, where if you register as a Telco, you had to have certain SLA's for your services offered, as they are essential services, even if offered by a private company.
I believe that is already in place, but does not cover mobile phones, only fixed lines.
