T-Mobile went from wireless giant to major fiber owner almost overnight — its joint ventures now run Lumos in the mid-Atlantic and Metronet across the Midwest and Southeast, building toward millions of new passings by 2030. Subcontract on any of those builds and you’re working a T-Mobile Fiber program: prime-spec limits, verified endorsements, and a COI naming the right legal entity. We build the package and issue same-day.

What T-Mobile Fiber program subs are typically required to carry — confirm your subcontract’s insurance exhibit, and note the JV structure when your COI is issued:
$1M per occurrence / $2M aggregate with additional insured status for the contracting entity — ongoing and completed operations — primary and non-contributory, with a waiver of subrogation. Endorsements on the policy, not description-box promises.
Statutory workers’ comp in every state your crews touch, with $1M employers liability. Compliance systems verify comp per state — multi-state crews need multi-state endorsement, not assumptions.
$1M combined single limit across owned, hired, and non-owned vehicles — with fleet and radius rated for how the routes actually run.
$2M–$5M over GL, auto, and employers liability on larger scopes and programs with higher flow-down limits. Following-form, so it inherits the endorsements underneath.
Boring, trenching, and underground scopes increasingly carry pollution requirements — drilling fluid, fuel, and disturbed soil are excluded by GL. Our CPL page covers the details.
T-Mobile Fiber work flows through joint-venture entities — your contract may be with a Lumos or Metronet company, not T-Mobile itself. The certificate holder and additional insured must match the entity on your work order, and an acquisition-era rebrand doesn’t change the paper. We track it so your certificate clears.
If your route sheets or work orders trace back to T-Mobile Fiber, this package applies to you.
Aerial and underground passings on Metronet and Lumos expansion builds across the Midwest, Southeast, and mid-Atlantic.
Installation and service routes as the fiber footprints light up new subscribers.
Backbone and distribution splicing across fast-moving multi-market builds.
Directional drilling in the dense suburban markets these JVs target — pollution liability increasingly rides along.
Small cell and backhaul scopes where the fiber program meets T-Mobile’s wireless network.
Crews following the program across states need comp and auto rated for every state on the route.
Generic agents quote limits off a checklist. We build to the program — endorsements, entities, platforms, and the scope your crews actually run.
Lumos and Metronet kept their compliance processes through the T-Mobile era — we issue certificates that match each program’s entities and platforms, and update fast when names change.
Additional insured on GL and auto, waivers where required, primary and non-contributory backed by actual endorsements — the details compliance platforms bounce certificates over.
Renewal certs issued before expiration, because program compliance systems flag lapses automatically and stopped POs cost more than premium ever will.
Boring and trenching subs get WC class codes that match the work, XCU-clean GL, and pollution liability priced up front.
What crews ask before taking T-Mobile Fiber work.
Contractually, usually a Lumos or Metronet entity — they operate as T-Mobile's fiber joint ventures. Your insurance must name the entity on your subcontract as additional insured; a certificate naming T-Mobile when the contract is with a Metronet company is the kind of mismatch that stalls onboarding.
The typical program floor: $1M/$2M general liability with additional insured (ongoing and completed operations), primary and non-contributory wording, waiver of subrogation, statutory workers comp with $1M employers liability, and $1M CSL commercial auto. Umbrella layers of $2M–$5M appear on larger scopes; boring crews increasingly need pollution liability.
The requirement structure carried over — the change that bites subs is administrative: entities, compliance platforms, and certificate holders can shift as programs integrate. Watch your work orders and reissue certificates when the paper changes; we do it in minutes.
Same day once bound. With payroll, vehicles, and scope ready, most crews are quoted and bound within one business day.
