The QChat Solution Benefits

Goodbye to Dialing Numbers. Hello to New Customers.Push-to-talk helps wireless operators achieve: Mobile subscribers who use PTT as a core service do so in order to increase the efficiency of communication due to the nature of their business and lifestyle. Customers have reported that as subscribers build up a community of other PTT contacts, they tend to stay with their operator longer and be less subject to churn. PTT helps convert medium-value subscribers into high-value subscribers, and high-value subscribers into loyal subscribers.
