Elon Musk’s SpaceX and T-Mobile US Inc have picked up a powerful critic of their proposal to offer phone calls via satellite, with AT&T Inc saying the plan risks interfering with existing wireless services.

Regulators “should reject SpaceX’s request to simply take it at its word that it will not cause interference” and demand more information before allowing the service, AT&T said in a filing with the Federal Communications Commission released Friday.
