Goal

Design a simple way for customers to order and download an eSIM — a digital version of a SIM card. There was low customer awareness and limited device support so, clarity and ease of use were key.

Exploration

I kicked off the project by mapping the existing SIM journey with the Product Owner and Solution Designer to see what could be reused from the existing journey. We worked with the technology team to understand what was feasible as this was a project heavily influenced by the technology.

Discovery

Our partner agency Spotless ran a survey to gauge awareness. Insights showed most users were new to eSIM, guiding us to simplify both language and flow.

Challenge

The technology team suggested users manually enter a 32-character code to activate their eSIM.
I pushed back as I knew that customers will struggle to activate their eSIM. I built a prototype to test the suggestion from the technology team.

Testing

We ran six usability sessions with the technology team observing. By the third session, it was clear: the manual version didn’t work for the customer.

Outcome

I finalised the designs and annotated everything for dev handover, and ran a walkthrough to ensure clarity.
The result: a seamless, customer-friendly eSIM experience with collaboration and fast iteration. The designs below is a selection of the screens. This shows how the customer will download the eSIM.
