Mobile Bill Dispute Evidence Checklist: Step-by-Step Gathering Guide
Follow this 12-item checklist for airtight proof:
- Download Bills: PDF/screenshots of 3-6 months; highlight disputes.
- Gather Contracts: Promo emails, app screenshots of plan details.
- Capture Texts/Calls: Transcribe via apps (carriers provide metadata: date/time/recipient).
- Request CDRs: "Super phone bills" with usage/tower data--gold for disputes.

Digital Proof Essentials (Screenshots, Texts, Logs)
Screenshots are court-admissible if timestamped/dated. Text transcripts prove intent (e.g., "No, I didn't authorize"). Carriers' CDRs validate--no content due to privacy, but metadata crushes lies (e.g., proving location via towers).
Super Phone Bills Example: Plaintiff claimed no clinic contact pre-accident; CDRs showed calls--case dismissed.
