Mobile network rollouts in emerging markets present both unprecedented opportunities and complex challenges due to infrastructure constraints, diverse consumer needs, and volatile regulatory environments. This systematic review critically evaluates the product management strategies that have been adopted in mobile network deployments across emerging economies. Drawing on peer-reviewed articles, industry whitepapers, and global case studies from 2010 to 2024, the study identifies recurring themes, best practices, and contextual adaptations in product lifecycle planning, market entry strategies, feature prioritization, and stakeholder alignment. A structured PRISMA approach was employed to source and synthesize relevant literature from major scientific databases, resulting in the inclusion of 84 high-quality studies. Findings reveal that agile product development, coupled with frugal innovation principles, has been instrumental in tailoring mobile services to low-income, high-density populations. Successful rollouts typically involved customer-centric design, iterative feedback loops, and modular product strategies that enable rapid localization and scaling. Moreover, partnerships with local governments, mobile network operators (MNOs), and non-governmental organizations (NGOs) emerged as critical enablers for mitigating infrastructural and logistical barriers. Product managers in these contexts often balanced short-term go-to-market imperatives with long-term sustainability and adaptability goals, leveraging both digital and analog distribution models. The review also highlights significant gaps in risk mitigation, data-driven decision-making, and post-launch performance measurement in several documented cases. Many mobile network rollouts lacked integrated KPIs linking product value to operational metrics such as network reliability, user satisfaction, and service affordability. The study recommends a hybrid product management framework that blends lean innovation, digital transformation, and stakeholder co-creation to improve rollout efficiency and customer adoption in emerging markets. This systematic review provides a foundational resource for telecommunications companies, product managers, and policymakers seeking to understand and replicate successful mobile network deployment strategies in similar environments. It underscores the strategic role of product management in bridging technological innovation and socio-economic inclusion in the mobile connectivity landscape of the developing world.
