Enhancing rapid response with T-Priority and Mission Critical Push-To-Talk (MCPTT) Service.

In an emergency, there’s no time for radio silence. You need quick, secure, reliable communications that you can count on. That’s why we created T-Priority, the world’s first 5G network slice for public safety. T-Priority delivers up to 5X the network resources of an average user with lower latency and faster speeds more consistently—and our priority and preemption features helps ensure your teams stay connected, even during large-scale events.


T-Mobile Direct Connect Mission Critical Push-to-Talk (MCPTT) services were designed to meet the needs of first responders. With the full breadth and benefits of the most advanced 5G network in America, these advanced communication tools can streamline emergency communications, enhance operational efficiency, improve safety, and drive better outcomes.

MCPTT provides instantaneous communication with the push of a button. With the nation’s largest and fastest 5G network, T-Priority gives you an advanced set of voice and data services tailored specifically for emergency response, including:

●     Priority and preemption: First responders move to the front of the line and maintain access when network congestion is extremely high.

●     Dynamic talkgroups: Location-enabled access makes it easy to create groups and organize communications.

●     Emergency calling and alerts: Instantly send urgent messages and mass alerts to the people who need them.

With T-Priority and MCPTT, you get lower latency for real-time communication, expansive coverage in cities and countryside, and advanced tools for streamlined operations. 

Land Mobile Radio (LMR), the longtime backbone of public safety communications, can be limited in both coverage and capacity—especially during large events or incidents that exceed the radio system’s coverage area or capacity. That’s where MCPTT comes in, adding a new layer of resiliency, redundancy, and end-to-end encryption to your emergency comms.

MCPTT augments existing communications by providing an alternate channel when your LMR system is overloaded or out of range. So, first responders can always access reliable and effective communications when they need it most.

Advanced 5G features can also augment conventional radio and offer a greater level of information sharing for data-intensive communications like real-time video, location tracking, files, and data. Plus, MCPTT can extend push-to-talk communications to personnel using devices other than radios, such as support staff or volunteers, so they can use smartphones or tablets to participate in mission-critical communications.


This integration can be done gradually so you can start experiencing the benefits of push to talk (PTT) service without completely overhauling your existing LMR infrastructure. By scaling up the use of MCPTT over time, you can achieve a cost-effective, integrated communication system and get the best of both worlds.

With MCPTT and our 5G network, you get the capacity and faster speeds you need for more data-intensive applications.

●     Rapid response: Field commanders can make instant calls and messages—both 1:1 and to groups of up to 3,000 users.

●     Real-time photo and video sharing: First responders can share live photo and video feeds from the scene of an incident.

●     Location tracking: Supervisors can accurately track teams in the field to coordinate effectively and ensure everyone’s safety.

●     File and data sharing: Teams can quickly exchange crucial documents, images, and other data, such as floor plans or medical records.

MCPTT also enables robust security features like end-to-end encryption and T-Mobile Secure Access Service Edge (SASE). A SIM-based, zero-trust network access solution, SASE gives you granular control over channels, data, and devices, streamlined security controls, and automatic authentication to minimize delays.


With the capabilities of MCPTT service and the expansive coverage of our 5G network—you can count on mission-critical communications with confidence and speed.
