Spectrum Mobile, Xfinity Mobile, and Cox Mobile are all hybrid wireless services owned by cable companies Spectrum, Comcast, and Cox, respectively.
The wireless offerings are only available to customers who are using their cable services, and therefore only offered in regional areas where the cable companies provide service.
Spectrum and Xfinity both operate on Verizon's network combined with their respective networks of hotspot locations. Cox's service is still relatively new and being rolled out, but it is operating on Verizon's network as well.
