AT&T was about to let every line on a family account pick its own plan, and nobody shopping for wireless had seen that before. The checkout assumed one plan for everyone, so both the idea and the flow needed rebuilding.
We shipped a flow that let every line pick its own plan, and it became AT&T’s default way to sell family accounts.

From the 2.0 study
Become the first wireless carrier whose acquisition flow lets a family choose the right plan for each line, meeting the needs of their family and monthly budget.
I kicked off with a comprehensive audit — our acquisition experience against Verizon’s, the only competitor with mix-and-match already in-market. The audit defined seven specific needs the new experience had to address:
Users seek context, guidance, and control.
I framed the problem around three user types: net-new customers switching providers, existing customers changing to the new construct, and existing customers adding a line with the option to migrate the rest. Two entry points compounded it — start with a device, or start with a plan. The framework had to handle all six combinations cleanly.
For the Wireless Plans landing page, we focused on educating users through multiple applications to enhance familiarity with the change and reduce hesitation later in the journey. Research showed users did not understand the term "Mix and Match," so we abstained from marketing buzzwords and used direct language like "You can now add different data options to each line." Real testimonials helped users see benefits through real-life situations, a sample bill reduced surprises, and a rich video reinforced how the new construct delivered value to multi-line accounts.
We made a few strategic shifts to simplify decision making, each tied directly to a customer pain point from research:
One Unlimited plan, two tiers
Features à la carte
Discounts on the bill
The strategic shift I pushed for was inverting the parent grouping: organize by line, not by decision type. Most flows ask you to pick all plans first, then all devices, then all add-ons. Ours started with “Who’s line is this for?” — humanizing the decision before any product showed up. It also gave the account side a cleaner billing breakdown and made it easier to split financial responsibility across family members. A guided linear flow reduced cognitive load, contextual modals answered common questions in place, and a sticky progress element kept the running total visible so every choice connected back to the cost.

Acquisition flow map
By and large, our vision tested well. The most surprising revelation was that although users said they wanted à la carte features, they were initially put off by the offering and assumed it was an upsell — they expected most items to be included. That signal helped us calibrate the threshold between what should ship inside a plan and what should sit alongside it.
Mix and Match asked families to unlearn the shared plan. The learn stage carried that weight, so the buy flow never had to explain and sell in the same breath. I now put a teaching stage ahead of any flow that sells a new model.
Three plans called Unlimited stopped people at the first choice. Once plain names held up in testing, customers stopped asking what Mix and Match meant and started asking which plan suited their kid’s line. I now test names before layouts on any pricing surface.
