## Description

Stop guessing which mobile carrier is actually cheaper. Most people only look at the advertised monthly rate, but they forget about the hidden costs like device payments, data overages, and local taxes. This MCP changes how you shop for service by giving your AI agent the math it needs to see the full picture. 

You can feed your specific household details into your AI client, and it will run the numbers across multiple providers. It handles the heavy lifting of aggregating service fees and hardware costs to show you the total cost of ownership. Whether you are managing two lines or ten, you can get a clear breakdown of monthly and annual expenses. It's a practical way to stop overpaying for data you don't use or paying for expensive device installments you could avoid.
