Frequently Asked Questions

  • Push-to-Talk over Cellular allows teams to communicate instantly using mobile data networks instead of traditional radio frequencies. Users press a single button to speak to individuals or groups in real time, similar to a two-way radio, but with nationwide coverage and advanced features such as GPS tracking and encrypted communication.

  • PTT works across all major South African mobile networks using 3G, 4G, and 5G connectivity, as well as Wi-Fi where available. This allows teams to communicate nationwide without range limitations.

  • Both options are supported. The solution works on standard Android and iOS smartphones, or on dedicated rugged Push-to-Talk devices designed for demanding field environments.

  • All communications are protected using enterprise-grade encryption. User authentication, access controls, and secure communication channels ensure sensitive operational conversations remain private and compliant with business security requirements.

  • PTT operates on a predictable per-user subscription model, eliminating the need for expensive radio infrastructure, repeaters, and maintenance contracts. Pricing depends on user volume and deployment requirements.

  • Yes. Because PTT operates over cellular networks, communication continues as long as mobile network coverage is available. Most South African network towers have backup power systems, allowing continued operation during loadshedding.

  • Most deployments can be activated within days. Users simply install the app or receive pre-configured devices, allowing teams to start communicating immediately without complex infrastructure setup.

  • Yes. Built-in GPS tracking allows dispatchers and supervisors to view real-time team locations, improving coordination, response times, and worker safety.

  • Unlike radios limited by range and infrastructure, PTT provides nationwide communication, encrypted voice, GPS tracking, private calling, messaging, and centralized management — all without maintaining radio towers or repeaters

  • Yes. PTT solutions can integrate with dispatch systems, workforce platforms, and operational workflows depending on deployment requirements.
