Messages from unverified toll-free numbers have been blocked since 31 January 2024. Forbidden use cases include lead generation, gambling and sweepstakes, high-risk financial services, debt collection, credit repair, cannabis, vape, URL redirects, URL cycling and snowshoeing. T-Mobile passes through non-compliance fees ($1,000 for 10DLC program evasion, $10,000 per content violation).
