Advertising Regulatory Scrutiny

T-Mobile US, Inc. · 2026-10-01 · Importance 25 · Surprise 42

The National Advertising Division (NAD) found that T-Mobile US supported comparative claims for its T-Mobile Fiber (T-Fiber) service after a challenge by Charter Communications. The supported claims covered speed, latency, peak-hour performance, scalability, and future-proofing relative to traditional cable internet. NAD recommended that T-Mobile modify its claim, “Break free from big cable contracts,” because the broader assertion that major cable providers necessarily require long-term contracts or early termination fees was unsupported.
