Top US phone firms reject call to delay 5G rollout

Two of the biggest US phone firms have rejected a government request to delay the rollout of 5G services this week.

The US Transportation Secretary Pete Buttigieg and the Federal Aviation Administration (FAA) made the request over concerns about aviation safety.

However, AT&T and Verizon did say they will implement temporary safeguards.

Plane makers have warned that C-Band spectrum 5G wireless signals may interfere with sensitive aircraft electronics and could disrupt flights.
