Kyocera Communications, Inc. (from Japanese: 京セラ Kyōsera) is an American manufacturer of mobile phones for wireless service providers in the United States and Canada.

KWC was originally formed in February 2000 when Kyocera acquired Qualcomm's San Diego, California-based terrestrial handset division.

On April 1, 2009, Kyocera announced the integration of KWC and KSTI, creating a new, consolidated division called Kyocera Communications, Inc. (KCI), with the headquarters remaining in their San Diego location.
