Digital transformation (DT) is fundamentally reshaping the telecommunications industry by introducing new business models, services, and infrastructure paradigms. This paper explores the scope, drivers, and outcomes of DT within telecom through a mixed-methods study incorporating case analyses, industry data, and expert interviews. Results show that technologies like 5G, AI, and cloud computing are at the forefront of enabling telecom innovation. DT improves network performance, enhances customer experience, and drives revenue diversification. However, it also presents challenges such as legacy systems, skills gaps, and regulatory constraints. The paper concludes by outlining strategic recommendations for telecom operators aiming to thrive in the digital era.
