An FTEU program is any program to which the  subscriber opts-in, with the result that the subscriber  receives Mobile Terminated (MT) SMS/MMS messages for which they do not incur any premium or  standard messaging charges from their wireless  carrier. The subscriber may interact with the service  by sending SMS/MMS messages (including, but  not limited to, messages for the purpose of opt-in,  opt-out and requesting help). The wireless carrier  may, at their discretion, charge the subscriber at  standard messaging rates for Mobile Originated (MO)  messages to the program.
