Big 3 carriers team up to hunt dead zones

The wireless truce no one saw coming

The U.S. wireless giants are planning to join forces on a new venture designed to reduce those annoying dead zones where your signal disappears the second you need it most. In a plot twist worthy of a boardroom drama, AT&T, T-Mobile, and Verizon are talking collaboration instead of just endless speed-test bragging rights.

Why this matters

If this actually gets rolling, the carriers could improve coverage without each one having to go it alone and burn cash building the same towers three different times. That’s good for customers, sure — but it can also be good for margins if the project trims some of the industry's usual capital-spending bloat.

What investors should watch

• Whether the venture is a real operational partnership or just a fancy memo with a logo on it
• How the costs and benefits get split among the three carriers
• Whether regulators give the whole thing the side-eye

Big picture: when telecom rivals start acting like roommates splitting the cable bill, it usually means the industry is trying to solve a very expensive problem without starting a price war.
