How 48 hours with customers created a $1.5B business in 90 days.

In his first job after business school, David was Director of Consumer & Small Business Marketing at AT&T Wireless — in the earliest days of cellular. Two analog providers per market, basic phones, calls only. No texting, no data.

The popular plan was $9.99 a month with zero minutes included, then $1.50 per minute — plus roaming charges between cities and long-distance surcharges on top. Usage was so expensive most people left their phones in the glovebox for emergencies; heavy users were a niche of salespeople and road warriors.

AT&T — which had once declared there was no market for cellular — had just bought its way in, acquiring McCaw Cellular for $12.6 billion and a network covering roughly half the U.S. population.

The goal: become the #1 wireless provider in every U.S. city. David's job was to run AT&T's proven sales-and-marketing playbook in the new PCS markets — half of AT&T's addressable opportunity — launching Chicago, Detroit, Cleveland, Cincinnati, and Indianapolis as test markets, coordinated with engineering as they lit up hundreds of cell towers.

The team executed the plan to the letter. Three days after the May launch of Chicago and Detroit, something was dreadfully wrong: empty stores, almost no volume through national retail. The launch was a dud.

David's boss two levels up, GM Bill Malloy, pulled him into his office:

"Dave, I can't look at our retail employees any more. You're a smart guy — figure out why our service isn't resonating, and give me your best recommendation on what we should do."

The question: why isn't it resonating, and how do we fix it — fast? He had 48 hours.

There was no time for focus groups, surveys, or in-home tests. David needed insight today — so he went down to the company store and spent the afternoon talking to every customer who walked in, letting them shop first, then asking why. Patterns emerged fast.

• Our rate plans were identical to everyone else's — no compelling reason to switch.
• The AT&T brand alone, though preferred, wasn't reason enough.
• Customers were afraid to use their phones, for fear of sticker shock.
• In new markets AT&T was the entrant, not the incumbent — which is why the "proven" incumbent playbook was failing.
• People buy cell phones because they want freedom.

He also heard Phoenix was testing "big bucket" plans — a higher monthly fee with a large bundle of minutes — and getting strong traction, though still charging for roaming and long distance. Within hours it was clear the HQ plan would never work in new markets. It had to be thrown out. Capitalizing on what he'd learned, David sketched an entirely new offer: AT&T Digital One Rate.

No one thought it could be approved — not least because it gave away long distance, the parent company's core revenue. But Bill Malloy was a maverick. He put his job on the line: "Let's do it." They launched on the 4th of July, with a special Nokia phone wrapped in the American flag.

Within days, Digital One Rate had changed everything. Stores were packed with lines around the corner. It transformed the regional wireless market into a national game — the new price of entry was a national footprint, a long-distance network, and simple anywhere-minutes good in all 50 states.

As customers felt the freedom and simplicity, behavior shifted: the cell phone went from an emergency lifeline in the glovebox to the primary — eventually the only — communication device people carried. By listening to customers, ignoring conventional wisdom, and taking a real risk, the team created a unicorn business in under 60 days. Entirely a judgment call.
