Why is it important to know your current data usage when evaluating cell phone plans?

Understanding your current data usage is crucial when evaluating cell phone plans primarily to avoid overpaying for unnecessary data. By analyzing your data consumption habits, such as how much data you typically use for activities like streaming, browsing, and social media, you can better select a plan that fits your needs without paying for extra data you don't utilize.

If you choose a plan with far more data than you require, you may end up spending more than necessary each month. Conversely, if you underestimate your usage and select a plan with too little data, you might incur additional charges or face throttling once you exceed the limit, leading to a poor user experience. Knowing your actual data usage helps in making informed decisions that balance cost and performance, ensuring that you only pay for what you need.

The other options, while related to cell phone service, do not directly address the financial aspect of choosing a plan based on data needs. For instance, concerns about speed or coverage are important but do not relate specifically to evaluating the appropriateness of data limits relative to one's usage patterns.
