To find the carrier's parent company, you can check the following lists:Email-to-SMS GatewayUnited States Mobile Virtual Network Operators (MVNO)If the carrier doesn't appear on one of these lists, they will need to be contacted to see if they have an email-to-SMS gateway that converts emails to texts, and if so, what the address is to do so.Once this is obtained, contact GoMotion Support and we'll add the carrier to the list.
