Hi Roy, I was informed by a few different providers that Time-Warner, Verizon, and Charter are the primary carriers for zip code 92557. I was also informed Dish Network handles up to Hemlock and pigeon Pass, so I guess it all depend on your geographic location. I hope this helps and have a great day. I would be more than happy to assist you and can be reached at (951) 358 9906. Have a great wekend.
