Sambar brings two decades of AT&T experience, including building 5G networks and designing the FirstNet public safety system, positioning T-Mobile to compete aggressively in enterprise markets where these skills are critical.

T-Mobile appointed Chris Sambar, former COO of Public Storage and 20-year AT&T veteran, as Chief Enterprise Officer effective no later than October 14, 2026. He will report to CEO Srini Gopalan and lead the company's SMB, enterprise and government businesses while scaling emerging growth opportunities. André Almeida was promoted to Chief Marketing, Brand & Broadband Officer.
Why it matters
Sambar built AT&T's 5G mobile network, led enterprise sales, and designed the FirstNet public safety network—government-backed broadband for emergency responders. His appointment signals T-Mobile is doubling down on high-growth segments beyond consumer wireless and positioning itself to compete in enterprise markets where these credentials matter.
What to watch
Sambar will focus on expanding T-Mobile's SMB and business customer portfolio and help scale emerging growth opportunities such as T-Ads and Physical AI (AI combined with physical devices). The leadership restructuring also places network, technology, product engineering and cyber under Chief Technology Officer Dr. John Saw to advance AI and 6G experiences.
T-Mobile's leadership restructuring reflects a deliberate strategic pivot outlined in its February 2026 Capital Markets Update. The company is moving beyond its core wireless business into enterprise, government, and emerging technology segments—a transition that required hiring someone with deep experience in both large-scale network infrastructure and business-to-business strategy. Sambar's 20-year tenure at AT&T, particularly his roles in 5G network design and FirstNet deployment, directly address that need; he brings credibility in government relationships and the technical depth required to credibly serve enterprise customers who demand reliability and innovation.
The simultaneous promotions of Almeida and restructuring under CTO Dr. John Saw underscore that T-Mobile views its next growth phase as fundamentally driven by technology and product—specifically AI and 6G capabilities integrated into consumer and business offerings. By consolidating network, technology, product engineering and cyber under a single CTO, T-Mobile is signaling that these functions are inseparable from its competitive strategy. The appointment of Sambar to focus on SMBs and emerging opportunities like T-Ads and Physical AI suggests the company intends to compete not only on network speed and coverage (its traditional strength) but on new business models and AI-powered services that typically require enterprise sales expertise.
