Slide one arm of a pair of angled tweezers under the metal neck of one of the coaxial connectors on the WWAN (cellular) module.

Lift straight up to disconnect the cable.

Repeat the process to disconnect the three remaining coaxial connectors.

Use tweezers to hold a connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again. Don't use excessive force.
