Carrier-Neutral Results.
ProBiz360 delivers carrier-neutral mobility for builders, DSP fleets, and operators. We benchmark AT&T, T-Mobile, Verizon, and managed mobility (e.g., MetTel) to deploy what actually wins in the field—eSIM-first rollouts, zero-downtime ports, chain-of-custody device handling, and audit-ready documentation. No quotas. No spin. Just measurable performance and support that escalates until it’s done.
The Mobility Advocate Your Budget Deserves.
Contracts, credits, and escalations handled—with receipts, not excuses.
Founder & Solutions Architect
Chris Calkins Jr.
Chris Calkins Jr. is the founder of ProBiz360 and a force for carrier-neutral, results-driven mobility. After 25+ years loyal to a single carrier, Chris made the hard turn to objectivity—comparing AT&T, T-Mobile, Verizon, and managed mobility options (e.g., MetTel) and deploying what’s provably best for each footprint. His edge is execution: eSIM-first deployment, zero-downtime port waves, chain-of-custody device handling, and audit-ready documentation that stands up to procurement, finance, and legal. With ScaleFusion and Intune as preferred MDMs, he delivers secure onboarding, real compliance, and integrations that work beyond the slideware. Chris is a relentless advocate—even if you stay with your current carrier—negotiating terms, validating credits, and escalating until issues are actually resolved. Built for builders, DSP fleets, and operators who measure outcomes, not promises.
