Important: Compliance When Sending SMS/MMS
When sending SMS or MMS messages to non-business consumer phone numbers, you will need to be aware of regulations and laws in the areas you are sending in.
If you will be sending to U.S. phone numbers, you are required to register your number for A2P 10DLC, and all messages you send are subject to the requirements of U.S. mobile carriers.
