Our Client, an International telecommunication company based in Switzerland and specialized in Prepaid Mobile Services, recently developed a new VoIP mobile app to propose low cost international calls. Open Web Technology was approached to re-invent digital touch points with customers. Thanks to this work, customers can now order, manage and recharge prepaid accounts from the web and from any mobile device.


Open Web Technology applied its four step methodology

Definition of the solution

Our project team worked closely with our Client to prioritize all required functionalities . We derived the technical specifications and coordinated the work of all stakeholders.

Design of the site structure and pages

We designed a simple navigation concept to allow intuitive access to all functionalities. Once the wireframes validated, we defined the styling requirements and created a visual identity.

Development, validation and deployment

We configured, built and integrated the various systems using an iterative approach, continuously gathering user feedback to offer an optimal customer experience.

Promotion of the mobile app

Based on our long-standing experience, we made a number of recommendations in order to optimize the app’s listing on the different Mobile App stores. We defined and monitored KPIs and implemented several SEO and SEM tactics to optimize traffic generation.


In three months, we successfully delivered the customer support platform which is now accessed by thousand of users daily on the Web and with mobile devices.
