I run SwitchNinja (switchninja.app), a cell phone plan comparison tool that helps people find the right plan and stop overpaying. I track pricing, features, and changes across 10 major carriers daily — T-Mobile, Verizon, AT&T, Mint Mobile, US Mobile, Cricket, Metro, Visible, Tello, and Straight Talk. I can speak to MVNO value, prepaid vs postpaid tradeoffs, carrier pricing trends, and how Americans routinely overpay $40–60/month on their phone bills.
