To sue T-Mobile, file in small claims court for damages from data breaches, SIM-swap theft, broken Price Lock promises, missing promo credits, or billing overcharges. Serve T-Mobile through its registered agent, Corporation Service Company. T-Mobile's arbitration clause exempts small claims and offers an opt-out, so the courthouse stays open. Most cases resolve within 30-50 days.
