Mission Critical
Push-to-Talk (MCPTT).

Mission Critical Push-to-Talk (MCPTT) leverages our 5G network to extend Push-to-Talk capabilities to first responders and critical infrastructure organizations beyond traditional Land Mobile Radio (LMR) systems.

Explore the benefits of Mission Critical Push-to-Talk solutions.

  • Priority and preemption: Leverage T-Priority on the T-Mobile nationwide 5G network for critical communications.

  • Enhanced situational awareness: Use location-based services, including dynamic area-based TalkGroups, live video streaming, and messaging.

  • Land Mobile Radio interoperability: MCPTT enables communication with any LMR system, bridging group communications between users.
  • Satellite connectivity: Expand your coverage with MCPTT and T-Satellite, staying connected even in the most remote areas.

  • Remote user management: Easily check remote users, disable, or re-enable the app if a device is misplaced or compromised.

  • Dedicated PTT-only device: Experience mission-critical communications without distractions with our Siyata PTT-only device, designed as a true LMR replacement.

T-Priority: For emergency response organizations. Coverage not available in some areas and may be impacted by emergencies; check your response area. WPS enrollment with USDHS required for enhanced network functionality (including priority access, preemption, basic performance baseline, and T-Priority Slice features). Features available on our network; not available while roaming. T-Satellite: Texting & select satellite-ready apps with compatible device in most outdoor areas in the U.S. where you can see the sky. Satellite service, including text to 911, may be delayed, limited, or unavailable.
