Upgrade Decoder is a self-help calculator and document tool. It is not a law firm, financial adviser, or carrier, and nothing on this page is financial or legal advice. Savings are not guaranteed: every promo amount, plan price, trade-in and resale figure is a seeded example value as of 2026-09 (confidence labeled per row), and the carrier's official promo page and your own agreement always govern.
