What is the quickest way to check if my SMS content violates carrier policy?

Cross-reference your message templates against the CTIA SHAFT guidelines (Sex, Hate, Alcohol, Firearms, Tobacco) and carrier-specific prohibitions. High-risk categories like cannabis, cryptocurrency, and payday loans are subject to zero-tolerance blocking on T-Mobile and AT&T.

How long do manual campaign reviews typically take?

While automated approvals can occur in 24-48 hours for brands with high Trust Scores, campaigns flagged for manual review by AT&T or T-Mobile typically take 3 to 7 business days to process, depending on the severity of the flagged content.

What are the standard penalty fees for 10DLC carrier violations?

Carrier pass-through penalties for severe network violations (like sending phishing links or severe SHAFT content) can reach $10,000 per incident. This is in addition to federal TCPA statutory damages, which range from $500 to $1,500 per unauthorized message.

Why did my campaign get blocked despite a high TCR Trust Score?

Trust Scores primarily determine messaging throughput limits. Even with a score of 100, carriers use real-time behavioral analysis and content filtering to block campaigns that exhibit volume spikes, keyword stuffing, or generate elevated subscriber complaints.
