MobileX Powers CallSign Mobile, New Wireless Service Built to Support the Veteran Community
CallSign Mobile Launches as MobileX Introduces New Hybrid Retail Model for Brands Looking to Offer Wireless Services to Their Communities
IRVINE, Calif. and BROOKLYN, N.Y. — September 14, 2026 — MobileX, the most customizable wireless service designed to save consumers money, today introduced a new hybrid retail model that extends its wireless technology to brands looking to bring their own mobile services to their communities. CallSign Mobile, a veteran-founded company built to serve and support the service-connected community, is the first brand to launch under this new model.
With CallSign, MobileX powers the wireless experience, while CallSign leads the brand, customer experience, and relationship with the veteran community. MobileX is making the model available to brands across industries looking to bring wireless services directly to their own communities.
The relationship with CallSign also extends beyond the technology, with MobileX Founder and CEO Peter Adderton serving as an advisor to the company.
“CallSign is exactly the kind of company we want to support as we expand what we’ve built at MobileX,” said Peter Adderton, Founder and CEO of MobileX. “We’re proud to partner with a company whose mission is to serve those who served. This is as noble as it gets. Giving organizations like CallSign the technology and wireless experience to turn that connection into something bigger is an exciting next step for us.”
CallSign was created on the idea that everyday economic activity, including something as routine as paying a mobile phone bill, can support the veteran community. From its first day of service, the company will direct $1 per line per month to the Signal Impact Fund, which supports organizations and initiatives focused on veterans, including those affected by traumatic brain injuries and post-traumatic stress.
“CallSign was built on a simple idea: something millions of people already pay for every month can also become a way to give back,” said Adam Marr, Co-founder and CEO of CallSign Mobile. “We’re creating a wireless service that gives the veteran community a way to stay connected while giving back to those who need it most. MobileX is helping us turn that idea into a service we can bring to our community.”
