10DLC Message Sandbox for Businesses

If you send text messages to customers, this sandbox helps you stay compliant before you send them. It simulates how major U.S. carriers such as AT&T, Verizon and T-Mobile review your messages for potential 10DLC issues like restricted words, payment requests or missing opt-outs.

Tip: Messages that mention loans, payments or personal details are often flagged by carriers. Use this tool to review and adjust your message before launching your campaign.
