The rapid development of information technology has led to a significant transformation in various sectors worldwide. In Africa, particularly South Sudan, where infrastructure and technological adoption are nascent, exploring the potential impacts of emerging technologies like 5G is crucial. A comprehensive search strategy was employed using databases such as IEEE Xplore, Google Scholar, and JSTOR. Keywords related to 5G, digital transformation, and African cities were used to identify relevant articles published between and . Studies were assessed for quality and relevance based on inclusion criteria. A total of 47 studies met the inclusion criteria. The findings indicate a growing interest in exploring the potential of 5G technology, with themes such as improved connectivity, enhanced data transfer rates, and increased reliability emerging prominently across various sectors including healthcare, education, and agriculture. While there is increasing research attention to 5G's role in digital transformation, there are notable gaps in terms of empirical evidence and practical applications specifically tailored for South Sudan's context. Future studies should focus on developing case-specific frameworks and pilot projects. Given the current landscape, it is recommended that policymakers prioritise investments in infrastructure readiness, alongside fostering a conducive environment for technological innovation and adoption. Additionally, collaboration between academia and industry stakeholders can facilitate knowledge dissemination and capacity building. Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.
