I boosted sales thanks
to eSIM implementation within SIM plans

Client: EE (retail)
Industry: Telco
My Role: Product Designer

As a premium brand, EE figured the necessity to include eSIM in its packages. Most of consumers were unaware of this technology, it was only a matter of time before it became desirable.

the brief

Development brief

My job was to implement eSIM in SIM-only plans within a short timeframe.

I had to avoid disrupting the current user journey. I needed to ensure customer satisfaction with the new features. Additionally, I needed to

prevent the incorrect ordering of eSIMs for phones that were not compatible.

I had 'carte blanche' to define my process within budget and timeline.

the challenge

The challenge

Any change on the product pages could impact negatively the sales. SIM plans

are a key revenue stream for the company, and any mistakes could have significant financial consequences for EE. I had a limited access to preliminary research to guide the project, with only user testing to validate the solution.

the process

The process

I compensate for the lack of discovery with desk research. I reviewed the previous research conducted on other features to extract valuable insights. I also use benchmarking to understand market trends. Additionally, I organised a user testing session to ensure my solution is at least viable and do not jeopardise the current sales.

the pain points

I figured the pain points

Activate eSIM was a challenge for clients. First it started with a printed QR code, sent by post. Later, the activation material was sent by email. I mapped solutions to every assumed pain points.

the user testing

I tested the solution

I had access to limited research for this project I still managed to gather insights. They were straightforward:

– Most participants were unaware of eSIM.

– Once informed, the majority of participants wanted an eSIM.

– There is a need for reassurance at every stage.

the benchmark

I benchmarked

Since this project focuses on a consumer product, benchmarking the competition was straightforward.


Notably, BT, EE's sister company, had already integrated eSIM into its consumer offerings. I reviewed and adapted BT's approach using our in-house design system. Throughout the process, I opted for an iterative design approach.

the roadmap

The roadmap

The project has been quite straightforward. I respected the roadmap that I established. I did not need to adjust the deadlines. At each step, I ensured there were no roadblocks and that nothing would prevent the project from being delivered on time and within the allocated budget.

the outcomes

Success and learning

Unfortunately, I don't have specific numbers to share, as I didn't have access to the analytics for this project. The insights I have come from the final user testing, which have been very positive. Processing time significantly reduced. Participants found all the

information they needed, leaving fewer questions unanswered. I learned the importance of keeping the user journey straightforward and applying simple solutions to complex problems.

Sorry, my portfolio is optimised for desktop experience. Stay tuned for the mobile version coming later this year
