Incoming SMS


Incoming SMS enables businesses or organizations to receive text messages from their customers or users

  • Customer initiates an SMS by composing a text message on their mobile device and sending it to a designated phone number provided by the business. This phone number can be either a short code (a shorter phone number, usually 5 or 6 digits) or a long code (a standard 10-digit phone number).

  • Exotel receives the message from the SMS gateway and sends the text message to the callback URL shared by the business. Exotel also stores the data SMS record for reporting purposes.
