In 2006 an article in the "International Herald Tribune", while praising the service's integrated billing option, stated "SMS.ac is one of those right-place, right-time, right-technology companies that has nearly all the elements for colossal success. But it also has hovering over it a big red flag that could wrong-foot it at any moment as some consumers had complained on the Internet and in the mainstream press that SMS.ac has charged them for services they never asked for, making that billing relationship into potentially its greatest liability."
