True Cost Calculator: Promo Price vs 24-Month Cost
Advertised prices hide three things: the step-up after the promo, monthly equipment and network fees, and one-time install/activation charges. Enter two plans and compare what you'd actually pay.
Taxes and regulatory pass-through fees are excluded (they apply to every provider). If a promo requires a contract, add any early-termination risk to your judgment, not the math.
