A major blind sport in mobile network operations could be solved by using SIM-based, device-side quality of experience (QoE) telemetry, according to independent research by Chetan Sharma Consulting for vendor Simphonic found.
Analysing 4,679 real-world device events collected over 30 days, the study found 40.5 per cent of negative subscriber experiences, such as dropped networks, voice call failures, modem restarts, and cell handoff disruptions, are largely invisible to traditional network KPIs, even though they strongly influence churn.
Notably, 59.4 per cent of the negative events occurred at subscribers’ primary stationary locations like home and work, where perceptions of mobile operator quality are formed.
The research proposes a customer experience index (CEI) which rolls up event severity, clustering over time, location “dwell” weighting, recovery effort, and stability into a single churn-risk score.
Operators using this framework “can automate churn intervention workflows, optimise capital expenditure with granular insight, and replace costly drive-test programmes with a continuous, anonymous aggregated signals from their own subscriber base”.
“The SIM is the vantage point where network behaviour and human perception intersect”, stated Chetan Sharma, CEO of Chetan Sharma Consulting. “Our analysis makes clear that customers don’t churn from networks — they churn from experiences”.
He noted operators who deploy device-side QoE intelligence “will have a measurable, defensible advantage in churn prevention, capital efficiency and customer trust”.
Alongside the research, the company rebranded from Wadaro to Simphonic to reflect a shift from SIM software to AI-driven orchestration of SIM-reported intelligence for real-time network operations.
It also announced a strategic equity investment from NAL Technologies (Naltec) to accelerate operator deployments.
The company’s Simphonic’s EdgeQoE platform runs as a lightweight Java Card applet operating passively on SIM and eSIM across device generations from 2G to 5G without impacting battery, performance or UI.
Simphonic stated the platform is already reporting billions of data points for tier-1 operators worldwide.
