Contel never saw the ocean side of the So Cal mountains.
The pockets of pre-GTE that were in the San Fernando Valley, Sierra Madre/Monrovia and Palm Springs was California Water and Telephone.
GTE took that over in 1967.
Contel showed up to take over some funky company that served Victorvile and Eastern Sierra Telephone that served Ridgecrest, the Owens Valley and the Eastern High Sierra. That was circa 1950.
Contel was never, ever in the Los Angeles Basin.
