Determining the carrier with the fewest dropped calls can vary depending on various factors such as location, network infrastructure, and individual experiences. Carrier performance can vary widely across different regions and even within different areas of the same city.
To get the most accurate and up-to-date information, I recommend checking independent studies and reports that evaluate carrier performance. Organizations such as RootMetrics, OpenSignal, and Ookla regularly conduct network performance tests and publish reports on carrier reliability and call quality. These reports consider factors like call drop rates, network speed, and coverage.
You can visit the websites of these organizations and explore their latest reports to get insights into carrier performance in your specific area. Keep in mind that while these reports provide valuable information, it's always a good idea to ask for recommendations from people in your local area who use different carriers to get a more comprehensive understanding of the network quality.
