If you try adding an SMS number to an Account or Member with a cell carrier that's not listed, first check our email-to-SMS gateway list to see if they are listed there.

If not, next check this list of United States mobile virtual network operators (MVNO) to see if they're listed there. If so, try selecting the real carrier used by the company and see if it works. If not, the carrier will need to be contacted to see if they have an email-to-SMS gateway that converts emails to texts, and what the address is if so. For example, even though Boost Mobile uses the Sprint network, <mobilenumber>@myboostmobile.com is used to send a text to someone through our system.

Please contact TU Support (click the Need Help tab on the right side of your site) with this information and we'll add the carrier to our list of SMS carriers.
