Client request

The key objective of the project was to create a user-friendly and intuitive interface that would allow users to easily activate and deactivate cards, monitor traffic usage, buy traffic packages and manage the cards lists.

The customer also expressed a desire for the app to reflect the needs of travelers, be easy to use and provide information on available carriers. He also stressed the importance of notifications and alerts on card status and traffic used.

Our role

Our task as a UX/UI design team was to create an information architecture, develop prototypes and design layouts that would satisfy client and user requirements. We paid special attention to navigational clarity, ease of use, and creating an enjoyable user experience.

Our team conducted research and analyzed user needs to ensure an optimal result. We strived to create a design that combines functionality, an attractive look, and alignment with the client’s brand.

In the end, our job was to create an effective and attractive user interface solution for the e-Sim card management application that would fully meet the customer’s needs and provide travelers with convenience and control over their communication capabilities.

Problems & solutions

Activating and deactivating e-SIM cards was confusing, inconvenient, and unnecessarily complex and time-consuming for users.


Lack of visibility into data usage meant that users could not easily track and monitor their e-SIM card traffic.


Users who traveled frequently and used multiple e-SIM cards encountered the problem of managing a large number of cards in a single application.


We simplified the process of activating and deactivating cards by making it intuitive and unambiguous. In the application interface, we used simple, clear steps to allow users to quickly perform the necessary actions.


To solve this problem, we added a feature in the app that displays traffic usage for each card, allowing users to easily see how much data they've used and how much remains. We also included the ability to set alerts and notifications for approaching traffic limits, ensuring users are always aware of their current status.


We added the ability to conveniently add, delete, and switch between cards, along with viewing information about each card separately. Additionally, we developed functionality to manage the list of cards, enabling users to easily manage their e-SIM cards.

Research stages

Research process

As part of our project work, we conducted extensive research:

  • We analyzed competitors by studying their apps, identifying their strengths and weaknesses, and assessing market trends and needs to develop a unique and competitive app.
  • Through surveys, interviews, and user observations, we gained insights into user needs, expectations, and behaviors. This informed the key features, interface solutions, and enhancements tailored to user needs.
  • From these studies, we defined the main sections, subsections, and functions for our application, organizing them to allow users to quickly and easily access the necessary functions and tasks.
  • We developed User Flows based on research into user behavior and tasks. This helped us determine the optimal sequence of actions and the logic for transitions between different screens and functions. As a result, we managed to create a seamless and intuitive user experience that minimizes unnecessary steps and effort for users.

Information architecture

We designed the application’s information architecture for logical, intuitive user interaction and task facilitation. Our steps included:

  • Information Mapping: We mapped out main categories and subcategories, organizing them logically based on user needs and tasks.
  • Structure and Navigation: Using our mapping as a foundation, we structured the app and defined navigation links, ensuring users could easily find the necessary information.

The result is a clear, systematic presentation of information and straightforward navigation, enhancing the user experience and task efficiency.

Stage 4

User Flow

We developed User Flows to optimize action sequences and enhance the experience. These flows help visualize the journey from start to finish and highlight potential improvements. Our approach included:

  • Identification of Key Tasks: Based on research, we identified essential tasks such as activating an E-SIM card, purchasing traffic, and viewing traffic usage.
  • Defining Steps and Relationships: We detailed the steps for each task and arranged them in a logical order to ensure smooth transitions. For instance, activating an E-SIM card involves navigating to the card page, selecting a card, and toggling it active.
  • Visualization: We created diagrams to depict these steps and their interconnections, clarifying navigation through the app interface.

By mapping out these flows, we made the app more intuitive and responsive, significantly improving the experience.
