eSIM Modernization is a UX design project aimed at increasing user awareness of eSIM technology, improving activation instructions, and streamlining the SIM swapping process within T-Mobile's online purchase and BYOD (Bring Your Own Device) flows.

eSIM - electronic SIM card prebuilt into phones so you no longer need to insert a physical SIM card.

SIM Swapping - when a person switches from a physical SIM card to an eSIM or vice versa.

MyTMO - The signed-in experience on T-Mobile's website.

The primary objectives was to improve user completion rates for eSIM activations, reduce customer service calls related to activation issues, and elevate overall satisfaction with the BYOD process.

This initiative focused on the newly adopted eSIM technology by phone manufacturers.

Introducing an unknown capability to millions of people

Introducing an unknown capability to millions of people

Before this project, 80% of T-Mobile's customers were unaware of eSIM technology. The lack of messaging and education about eSIM led to extensive customer service calls due to failed eSIM activations.

The goal was to enhance user understanding and ease of use, preparing T-Mobile for the new iPhone release.

Our approach

Our approach

User research and analysis

Conducted initial user research and reviewed existing research related to our project. Focused on the current BYOD experience, MyTMO, and SIM Swapping.

Streamlining user flows

Ideated solutions to minimize steps and avoid technical jargon people wouldn’t understand.

Simplifying technical details

For necessary technical jargon (e.g., IMEI and EID numbers), used modals to provide options for learning more.

Design variations

The designs were generally similar, with differences in copy and button placement.

Design evaluation and team feedback

We presented our top 3 designs to the team, discussed each, and chose the best design to continue with and test.

Testing our design

Testing our design

The UX research team used remote unmoderated usability sessions, task scenarios, and a survey. There were 15 participants in total. The numbers cannot be shared due to an NDA but I can share some of their quotes.

"It was easily communicated and I knew where to go next and what to expect after putting in my IMEI number and choosing the eSIM option. It was all right there for me on the page and flowed easily for me to understand the next steps in the process."

"I felt somewhat confident because I wasn't 100% sure how I was going to activate my phone until I got to the very end. I think if I was provided with activation instructions earlier on, I would have felt more confident."

"I loved how easy it was to see the list of needed info, lists of things to do once I placed my order, and how clean and simple the process was."

Changes implemented from testing

Changes implemented from testing

Copy refinements post-testing

We tweaked the copy on the BYOD and activation pages following the testing.

Technical constraints

We were constrained with what we could introduce for this experience so using something like a stepper was impossible.

Future enhancements already designed

More extensive changes were also made for an upcoming experience that has not been released yet so I cannot share them until then.
