Cable broadband operators have proved again that they are a potent source of competition in the mobile wireless market. During the first quarter 2022, Charter gained 373,000 net subscribers to its Spectrum Wireless service. This raised Charter's wireless subscriber base to 3.9 million as of the end of the first quarter, a 47.2% increase compared to a year earlier. Meanwhile, Comcast gained 318,000 subscribers to its Xfinity Mobile service. At quarter's end, Comcast's wireless subscribers had risen to almost 4.3 million. And Altice added 12,000 subscribers to its Optimum Mobile wireless service during the first quarter, reaching a total 198,000 subscribers.
Free State Foundation Legal Fellow Andrew Maglouglin and I called attention to the quick rise of cable mobile virtual network operators (MVNOs) and their benefits to wireless consumers in our Perspectives from FSF Scholars, "The Broadband Internet Services Market in January 2022: 5G, Cable, Fixed Wireless, Wi-Fi 6, and Fiber Are Benefitting Consumers." The impressive first quarter 2022 results reported by cable MVNOs indicate that consumers are continuing to take interest in these innovative choices for wireless services.
Aside from positive subscriber addition numbers for early 2022, the competitive outlook for cable MVNOs is strong because of their ability to leverage their existing cable and wi-fi network infrastructure to offload mobile wireless traffic. It is reported that about 85% of Spectrum Mobile subscribers' mobile usage goes through Charter's Wi-Fi network. And Charter's joint venture with Comcast to offload traffic using CBRS spectrum reportedly is in early trial stages. Expect to hear more about cable's growing stature in the mobile wireless market.
