As we know, SMS is one of the most valuable channels to connect with customers. With the rise in popularity of SMS as a channel, we're seeing a rise in spammers and businesses operating in unsupported categories as defined by the major wireless carriers. SMS traffic is highly regulated and as a result, there are categories of businesses using SMS that are not supported by wireless carriers.

Unsupported businesses primarily include age-restricted businesses or businesses without federal approval. If your business operates in one of the following categories, unfortunately, SMS may not be the right channel for you at this time. As defined by our acceptable use policy, your account will be subject to closure.

First party loan content is acceptable if it is not promotional messaging, unless it is on an approved Short Code.

Businesses that solely operate in stocks, investing, or cryptocurrency are only permitted to send SMS traffic that is 2FA and/or transactional messaging. If there is a mixed use case where that is a partial aspect of the business, it may be approved based on the other use case content.

Debt collection or forgiveness

  • Third-party debt collection
