What do you need to know?
To send messages in the US, you must register all 10DLC phone numbers. As a result, AT&T and T-Mobile are increasing the per-message rate on unregistered traffic to motivate unregistered senders to register. If these numbers remain unregistered, they may be subject to additional filtering or blocking.
Some carrier fees will be increased on June 1, 2023, and others will be increased on August 1, 2023.
