A busy and productive MWC Doha for the Cellusys team, from customer meetings to industry discussions across the GCC. One of the key sessions this year was Ooredoo Group’s roaming roundtable, facilitated by DT Economics LLP, where Dawood joined regional leaders to explore how the GCC can build on modern network rollouts and new AI-cloud capabilities to reset roaming services in a more integrated, future-ready way. Great conversations all week, looking forward to the next one.
