# Outbound SMS

When you send an SMS to a phone number belonging to an end user's device you are sending an Outbound SMS. Historically, this was and still is referred to as a Mobile Terminated (MT) SMS, though nowadays an SMS is not always sent to a mobile device. In an Outbound SMS you can set the From or Sender field with whatever you have registered or purchased with Infobip, either a Long Number, Short Code, or text based Sender.
