In line with vast technological disruptions and advancements, some telcos have stepped in to the process of API-fication having thought of increasing their revenues and to overcome revenue pressure to sustain in the digital services sphere. The question is how do APIs make it possible for telcos to earn recurring revenues? Is it really possible for telcos to make money just by merely opening up APIs? The answer is No. Leveraging telco assets to spearhead competitive advantage is not solely dependent on opening up telco APIs. Therefore, Telcos need focus on an API strategy which really helps them to conquer in the face of digital transformation.
