In the case of MT-services, users are charged for messages received rather than for messages sent. This setup is very convenient for subscription-based, recurring services that may be, for example:

• daily horoscopes, biorhythms;
• daily jokes;
• daily sports scores;
• daily news alerts;
• weather information;
• traffic information;
• daily business information (e.g. stock or currency info);
• event triggered alerts (e.g. sports, stock exchange, FOREX)
• etc.

In the case of such services, users only have to send in a single SMS message to subscribe. Content will then be sent to them regularly (or on an event-triggered basis). When it is time to renew the subscription, users will automatically receive an appropriately charged MT billed SMS message.
