This document analyzes a customer's mobile bill from Vodafone to understand usage patterns and recommend an optimal plan. The summary is: The analysis found that most calls were to local Vodafone numbers during peak hours. Data usage was highest on weekends. The current plan costs Rs. 848 per month but a recommended Reliance plan offering 500 free SMS and 1GB data for Rs. 321 would save money, along with an optional 2GB data pack for Rs. 235. Demographic analysis estimated the customer is a female aged 25-30 years old, working professional using a 3G smartphone.
