As announced by The Campaign Registry (TCR) in September 2022, all businesses that want to use SMS messaging must register with wireless carriers. While each carrier (eg. Verizon, AT&T, T-Mobile) may have some nuances to the process, Agent Legend facilitates the entire process for you here. It involves verifying your business information, purpose, and intended usage. If you don't register with carriers, you may face issues with message delivery, additional fees, and even account suspension.
