What is the correlation between prepaid connections and network reliability?

Question

Accepted Answer

Prepaid Connections Show a Negative Correlation with Network Reliability

Opensignal's analysis indicates a discernible negative correlation between a high prevalence of prepaid mobile connections within a market and the overall Reliability Experience scores. This suggests that as the proportion of prepaid users increases, the measured reliability of the mobile network tends to decrease. While the specific causal mechanisms are not detailed, this observation aligns with broader trends in emerging markets where network infrastructure may face challenges in keeping pace with evolving demands.
Market Dynamics and Reliability Scores

Markets experiencing higher growth rates in their mobile customer base have been observed to exhibit lower reliability scores. This phenomenon is partly attributed to the dual pressures faced by telecommunication providers in these regions. Firstly, there is a continuous need for substantial network investments to accommodate the rapidly increasing and evolving data demands of a growing user base. Secondly, existing network infrastructure may not always be adequately designed to anticipate the coverage and propagation requirements of newly developed urban areas and construction projects.
Understanding Network Reliability Metrics

Reliability, as defined by Opensignal, quantifies the consistency with which users remain connected to their mobile network and can perform essential tasks such as sending emails, streaming videos, and using navigation applications without interruption. This metric is considered by mobile users to be of paramount importance, often ranking second only to cost when evaluating carrier services. Survey data indicates that a significant percentage of users, 19 per cent in the US Household Survey 2023, identify reliability as the primary factor in their carrier evaluation, surpassing the importance placed on download or upload speeds by a considerable margin.
Factors Influencing Reliability Experience

The relationship between network speed and reliability also warrants attention, as higher speeds do not automatically translate to better reliability. Opensignal's findings suggest that Reliability Experience scores tend to improve significantly up to average download speeds of approximately 25 Mbps. Beyond this threshold, the impact of further speed increases on reliability diminishes, showing a much slower rate of growth, particularly for markets with average speeds exceeding 50 Mbps. This indicates that while speed is a factor, it is not the sole determinant of a reliable mobile experience, and other infrastructural and operational elements play a crucial role.
