Use the Ad Group Carrier Settings to set the carriers on/off status at the ad group level from your Mobile Sponsored Search account. All carriers are Online by default.

Note: For ads to be served to users of a specific carrier, the carrier must be selected (Online) at all levels. If you unselect (Offline) a carrier at the ad group level, then by default, that carrier will also be Offline for all new ads in that ad group.
