T-Mobile International Roaming

I served as Design Lead (UX/UI), overseeing a junior designer to deliver an updated experience for checking coverage internationally. I worked closely with Product Managers and T-Mobile’s user research team across multiple iterations to refine flows and messaging, ensuring customers could easily understand coverage, rates, and device compatibility so there are no surprise charges on their bill while traveling, providing peace of mind.

The challenge

Users have difficulty locating international roaming information on T-Mobile’s website, which causes frustration and prevents quick access to essential details like coverage maps, per-country rates, device support, and travel-specific plan options.

Our design approach

We designed and tested a streamlined experience that elevates International Roaming and Cruises, benchmarking against leading telecom and travel sites. The solution focuses on clearer information architecture, simplified search and filtering, concise on-page explanations, and interactive coverage visualizations to help users find what they need faster and with more confidence. We also implemented the ability to search multiple destinations and devices at once so customers can be sure everyone on their plan is covered at every destination in their trip.
