Telefonica O2

Portal and mobile application for management of tariffs and
customer's mobile services.

Challenge

Do you remember those times when you had to go to a customer service point or call a hotline to change the tariff or account information, incurring considerable connection costs? We remember. We also remember all the work we put into changing this state of affairs.

Together with Telefonica Germany GmbH & Co OHG – more commonly known as O2 – we have changed the approach to handling broadband and mobile services such as minute packages and data packages. The challenge we faced was to create a system that would enable immediate access to tariffs and mobile services from anywhere in the world, without the need to use a hotline or visit stationary points. In addition, the solution was to be flexible enough to be quickly deployed to different customers in configurations tailored to their needs.

Solution

We have created a portal and a mobile application used by over 50,000 users.

They enable the selection of tariffs and their personalization, insight into the statistics of telephone calls, sms / mms, mobile data consumption and the costs of tariff plans. This solution gives the user the ability to make changes to current services and personal data, download documents (e.g. invoices) and top up accounts.​

We have also implemented this solution in personalized configurations for other O2 clients: Saturn, Kaufland, Türk Telekom, Kabel Deutschland.

EO Customer Feedback

Aidan Johnstone
Telefonica O2

I had the pleasure of working together with eo Networks for 8 years, between 2012 and 2020. The one thing that I appreciated most as a customer was that whenever faced with new challenges eo Networks demonstrated an unwavering commitment to pragmatism and this allowed us to always focus on achieving the best results. The team was dedicated, efficient and highly competent. The biggest complement I can pay is that it was fun working with the team and I would do so again if the opportunity arose. I’d like to thank eo Networks for their great commitment – they made my product feel like our product.
