This was a project I worked on several months ago (mid-2025), and it's still in development (by late October).

It's the redesign of USIMS, an eSIM data service provider for roamers and travelers in more than 120 countries.

The app allows users to sign up and purchase and manage eSIMs and various data plans.

I participated in the design of a couple of concept screens (the ones shown here) for this app, and then I was contracted to design and prototype the whole app (which I can't show yet due to confidentiality matters).

These were the initial concept screens:

And this was the initial style guide:

By this initial version of the project, the Figma file looked like this:

I organized the Figma file intuitively and componentized everything, as well as creating a handy style guide and a set of styles and variables/design tokens to use throughout the interface in order to keep things consistent.

I ended up designing more than a hundred screens for this app, and then wired an interactive prototype to showcase how they'd work together, and worked to make the deliverables as easy to handle as possible.

As I said, the app is still in development up to this day (late October 2025). But it's going strong --several things have been changed and improved from this initial concept, but the overall idea and style stayed the same.

So that's it for this project (for now).

I hope you have a great rest of your day,

Godspeed 👋
