SA Voice Services Market Forecast & Analysis

This study provides a quantitative analysis and forecast of the South African fixed line and mobile voice services markets as a whole, and a more detailed focus on the largest segments.

Quantitative analysis and forecasts

A key objective of this study is to provide up-to-date market sizing and forecasts, while illustrating the major trends currently and those expected in the next five years. These include: fixed mobile substitution, fixed mobile convergence, service bundling, flat rate pricing, interconnection pricing including the effects of regulatory changes on voice services, services-based competition and drivers and enablers for widespread VoIP uptake.

The study is based on a combination of primary and secondary research and analysis, including an update of BMI-T’s baseline voice services model.

The underlying market model is a top-down model based on information collected from service providers (i.e. where broad data on revenues, subscribers, and ARPUs are available from operators), and bottom-up (number of connections/subscriptions per customer group, service penetration, traffic minutes by route, and average revenue per line or service per customer group). The analysis is also informed by BMI-T's most recent corporate and SME user surveys. Forecasts are based on a market scenario analysis, which includes a review of international trends as well as the specific nuances of the local South African environment, including future regulatory and competitive industry dynamics.
