Client Overview

Clear Mobitel is a UK-based mobile connectivity provider offering eSIM and SIM services across the UK and Europe. The company already had native mobile apps (iOS and Android) for their customers. To extend reach and give users a seamless experience on the web, they needed a professional marketing website and a dedicated web application where customers could buy new SIMs, top up, manage plans, and access the same services available in the mobile apps—all from the browser.

What I Delivered

• Website (CodeIgniter): A modern, responsive corporate website built with CodeIgniter that presents Clear Mobitel’s brand, services (eSIM, SIM, data-only, data add-on), and value proposition. The site is optimized for clarity, speed, and SEO and directs users to the web app or app stores.
• Web Application (Flutter, Dart, Firebase): A full-featured web app where users can buy new eSIM/SIM, top up, view and manage plans, and access account features—complementing the existing iOS and Android apps. Built with Flutter and Dart for a consistent, responsive experience, and Firebase for backend services. I also handled deployment of the web app.
