Challenge

People buy a mobile plan only a handful of times in their lives — and it usually meant a sales callback or a store visit. Vodafone wanted to replace that with a flexible, subscription-based eSIM plan, fully managed in-app. The hard part: making something as unfamiliar as eSIM feel as easy as any other subscription.

My Role

I joined from day one. I helped validate the initial concept, built functional prototypes for user testing, and briefed the research agency on focus areas — especially eSIM activation. In production, I delivered the final UI for the app and the launch landing page.

Result

Shipped as a digital-first mobile plan on iOS and Android. Customers now purchase, activate, and manage their plan entirely in the app — including upgrading, pausing, or cancelling — with no callback or store visit needed.

Design Process

I helped validate the initial concept and explore product positioning.

I then designed UI flows and built functional prototypes for user testing, briefing the research agency on the areas we needed to learn about — especially eSIM onboarding and activation.

I iterated the designs based on what testing surfaced, and in production delivered the final UI for the app (onboarding, plan management, upgrade / pause / cancel) and the landing page for the launch campaign.

Build a flexible mobile plan as a subscription?

Purchase the Plan

Unlimited data, unlimited calls and messages — all in a simple flow. No need to visit a store or deal with unnecessary obstacles.

Purchase

Activate eSIM

A fully digital eSIM process. If you prefer eSIM, just select it and activate your plan right after completing the purchase.

Onboarding

Manage Subscription

You can control your spending for the upcoming month at any time. Cancel anytime. Upgrade to higher tiers or pause the plan when you don’t need it.

Subscription

Payment Flows

All payments are handled automatically — a new approach for Vodafone Czech, where payments were previously invoice-based and required manual customer action.

Design Iterations

I started by analyzing the requirements and the current state of the design system to identify workflow bottlenecks. Then I ran interviews with designers actively using the system, asking each the same question: where do you see gaps and friction in your workflow today?


We brought the findings into a team workshop to identify, organize, and prioritize what we'd uncovered. To pressure-test our thinking, I demonstrated industry best practices — showing how mature design systems handle the same problems we were facing, especially around flexible theming token structure.
