Problem
Mobile tariffs were difficult for customers and sales staff to understand, while contract complexity undermined the customer experience.
Organization formation / Transformation / Telecommunications
Our team helped O2 rethink mobile tariffs around customers rather than contract complexity. We turned research into an immersive customer journey and tangible tariff concepts; the resulting Customer Experience Trail became training for employees and partners.

The brief
Mobile tariffs were difficult for customers and sales staff to understand, while contract complexity undermined the customer experience.
Help O2 compete through a customer-centered strategy and make tariffs easier to understand.
The work had to connect customers’ needs with shop staff, call centers, and the people inside O2 who designed tariffs.
Build an experience that could change how the organization understood customers and become reusable employee and partner training.
Process
We followed the journey from choosing a contract to buying, renewing, or leaving. We spent time with customers, worked in O2 shops, listened in call centers, and examined how tariffs were designed.
We saw frustrated customers who wanted devices, not complicated tariffs. Complex tariffs led many customers to delegate decision making to someone they trusted. O2’s core tariff offer was broken and required the entire organization to fix it.
Rather than present another slide deck, we built a tunnel that let clients physically experience the journey’s pain points. We then expressed new tariff concepts through wearable T-shirt prototypes.
The CX Trail was replicated at German HQ and later at Telefónica’s Global HQ in Madrid as well as at other hubs in Latin America. It became required training for all new employees, agencies, and vendors as O2 grew.
We examined contracts alongside the experiences of customers, shop staff, call-center teams, and tariff designers. The challenge was to make tariffs understandable for both customers and salespeople.
Time with carefully selected customers exposed the needs behind purchase and renewal decisions. Research observations were collected and connected into a shared evidence base.
Customers were overwhelmed by information and often delegated tariff decisions to trusted experts. Three attitudes—skeptical, expert, and trusting—helped the team understand different responses to complexity.
We built an immersive tunnel around informing, procrastinating, delegating, monitoring, and quitting or extending a contract. Walking through those moments made customer frustrations tangible for the client team.
T-shirts became prototypes for communicating tariff ideas without pricing tables. The word-of-mouth concept made a possible offer concrete and discussable.
Concepts explored sharing data to pay less, adapting to changing life phases, donating unused minutes, and group or organization tariffs. Each used a wearable message to express its central idea.
Replicas at the German and Madrid headquarters extended the trail beyond the original project. The deck reports training for more than 20,000 employees, franchisees, and vendors, alongside subsequent O2 business results.
