• Looking at the estimation context, this appears to be a market size estimation focusing on annual sales volume. Is that an accurate interpretation of what we're trying to estimate?

Why it matters: Determines whether to focus on new sales or total active devices Expected answer: Yes, annual new phone sales Impact on approach: Will calculate based on new purchases rather than total phone ownership

• Considering the diverse nature of the Indian market, should we segment our estimation by urban vs. rural populations or income levels?

Why it matters: Significant differences in purchasing patterns and phone preferences Expected answer: Yes, segmentation would be valuable Impact on approach: Will use separate calculations for different market segments

• Given the rapid pace of technological change, are we including both smartphones and feature phones in this estimation?

Why it matters: Different market dynamics and pricing for each category Expected answer: Yes, include both types Impact on approach: Will need separate calculations for smartphones and feature phones

• Considering India's large grey market, should we focus only on official sales channels or attempt to include unofficial sales as well?

Why it matters: Could significantly impact total sales figures Expected answer: Focus on official sales, but acknowledge grey market Impact on approach: Will base calculations on official data, with a note on potential underestimation
