• Looking at the timing, I'm thinking there might be a seasonal component. Has this drop coincided with any particular events or time of year?

Why it matters: Seasonal trends can significantly impact user behavior and purchasing decisions. Expected answer: No significant seasonal events noted. Impact on approach: If seasonal, we'd focus on historical data and cyclical patterns.

• Considering the magnitude of the drop, I'm wondering if there have been any recent changes to the product or marketing strategies. Have there been any updates to the prepaid plans or promotional activities in the past 1-2 months?

Why it matters: Recent changes could directly correlate with the activation drop. Expected answer: A new competitor entered the market with aggressive pricing. Impact on approach: We'd need to analyze competitive landscape and our value proposition.

• Given the specificity of the drop to prepaid plans, I'm curious about our postpaid performance. Has there been any unusual activity or growth in our postpaid plans during the same period?

Why it matters: This could indicate a shift in customer preferences rather than a loss of market share. Expected answer: Postpaid activations have remained stable. Impact on approach: We'd focus on prepaid-specific factors rather than overall brand issues.

• Thinking about potential technical issues, I'm concerned about our activation process. Have there been any reported problems or changes in the activation system or customer onboarding flow?

Why it matters: Technical glitches could be preventing willing customers from activating. Expected answer: No significant technical issues reported. Impact on approach: We'd shift focus from technical to market-related factors.
