MO SMS

MO (Mobile Originated) – message transmission from a handset device to a client (program) or application.

MO service is often used as part of 2-way SMS service (MT/MO combination).

In this case, companies send MT message first and receive a response from the end user.

Example :

MT : To unsubscribe from this newsletter reply STOP.

MO : STOP  (it will automatically be forwarded to the MT sender)

The service provider is assigning a certain Sender ID (long or short code) and the Client might receive MO messages from the end users, sent to the designated Sender ID. The procedure looks similar to the standard MT flow, only the other way around, with message originating on the mobile device.

  4. Subscribing to newsletters

Basic MT flow

 

In reality though, to be able to send a message between a PC (or other app) and mobile handset, you would need to use messaging service of SMS Gateway Providers. And the overall flow would look a bit more complicated :

The message is sent from the CLIENT’s app or server to SureM’s platform, forwarded then to the respective carrier and all the way to the handset.
