• Looking at the timing, I'm thinking there might have been a recent change in the service. Has there been any significant update or modification to the international roaming service in the past month?

Why it matters: Recent changes often correlate with satisfaction drops. Expected answer: Yes, a new billing system was implemented. Impact on approach: If true, we'd focus on the new system's impact on user experience.

• Considering the metric, I'm curious about its components. Is the 10-point decrease uniform across all aspects of customer satisfaction, or are certain areas more affected?

Why it matters: Helps pinpoint specific problem areas within the service. Expected answer: The decrease is primarily in billing satisfaction and network connectivity. Impact on approach: We'd prioritize investigating these two areas first.

Why it matters: Could indicate localized issues or global system problems. Expected answer: The decrease is more pronounced in European countries. Impact on approach: We'd focus on European-specific factors and infrastructure.

• Thinking about user segments, I'm considering if this affects all customers equally. Is the satisfaction decrease consistent across different user types (e.g., business vs. leisure travelers)?
