Wireless Priority Service (WPS) enrollment ensures priority access and preemption on our reliable nationwide VoLTE network. Calls placed with WPS are prioritized end to end regardless of the carrier on the other side.
WPS eligibility must be confirmed by USDHS. WPS functionality (including priority access and preemption) may not be available while roaming; may default to 4G signal in areas with standalone-only 5G. Completion of calls not guaranteed.
