Wireless Priority Service (WPS) for Emergency Calling

Priority access & preemption on T-Mobile.

1

The importance of WPS.

WPS is vital to national security and is administered by the Cybersecurity & Infrastructure Security Agency (CISA, part of DHS). It ensures priority access to cellular and landline networks for critical infrastructure agencies.

2

Registration is easy.

T-Mobile registers eligible organization lines for WPS at no charge and uses WPS enrollment to assign priority and preemption status for calls and data. No user action is required.

3

Assuring call completion.

If there is congestion on another network, a customer can obtain WPS-assigned priority for their call by dialing *272 or using a Priority Telecommunications Services app for cross-carrier calls.

The Department of Homeland Security determines WPS eligibility.

Why use WPS?

WPS is the only way to assure end-to-end voice call prioritization. On WPS-registered lines, T-Mobile provides priority access and preemption for voice and priority access for data. If congestion occurs on other networks, WPS users can obtain receiving-network priority, but not preemption, by dialing *272 or with the Priority Telecommunications Services app.
