About CellularOne


Enhancing people's lives through wireless communications is our mission at CellularOne. As a leading wireless communications company in San Luis Obispo County, we use the most advanced and progressive technology to provide the products and services customers desire.

Since opening our doors to SLO County wireless customers in 1995, our vibrant, privately owned company has become the fastest growing network in the area, adding more cell sites than any other wireless provider on the Central Coast.

CellularOne recently experienced a major milestone with the implementation of our new digital switching center. This $5 million investment includes a new switch, as well as a new voicemail system and mobile messaging center. The new digital platform will benefit our customers in many ways. It will enable us to offer new voice and data services and features; provide better reporting of billing information; and enhance our response time to network issues. Our customers now receive a more efficient and higher level of customer service than ever before.

As a locally owned and operated business, CellularOne is committed to our community and sponsors several charities and non-profit organizations. We are an avid supporter of the Breast Cancer Early Detection Program, SLO Symphony, and Hospice of San Luis Obispo County. CellularOne has also donated more than $25,000 to Cuesta College Athletics as a gesture of our strong belief in supporting college sports. CellularOne also created a scholarship program at Cal Poly to assist selected students in the university's journalism department.

These are exciting times as wireless technology improves our ability to stay connected with each other. The flexibility and convenience that is inherent in wireless communication has led to its phenomenal growth around the world.

At CellularOne, we are proud of our reputation on the Central Coast and have set the standard for quality systems, superior coverage and local customer service.
