Virtual private sex chat
Unused minutes were rarely usable on a second call.The provider provided (say) 10 minutes of service, but got to keep all of the money (say 20 minutes).(This attitude still survives among some providers.) When public (mostly female) pressure forced the phone companies to stop providing this service to sex workers, a transition was made to a manual method: pre-paid blocks of time, 10, 30, 60 minutes, whatever the customer would pay for.The incentives for providers were then reversed; rather than earning money from keeping the customer on the line (orgasm delayed), they earned more from bringing the caller to orgasm quickly, so as to move on rapidly to another call.One last word of caution, the chat agent jobs for phone actresses are sex chat operators — just want you to be aware of what you're applying for if you run across these.
With the progress of technology it became more practical, convenient, and economical for providers to work out of their homes.
Details vary significantly from one platform to another, but the provider may be given a personal page on the platform to use however she (sometimes he) wishes.
