  • The process begins with a user or an application initiating an SMS message. This can be triggered by a person sending a text message from their mobile device or an application generating an automated message.
  1. Message Aggregation:
  • The SMS gateway aggregates messages from different sources and formats them into a standard SMS format that can be transmitted over the telecommunication network.
  1. Routing:
  • Once the message is formatted, the SMS gateway determines the most efficient route for delivering the message. This may involve selecting the appropriate telecommunication carrier or network to ensure timely and reliable delivery.

  • The SMS gateway transmits the formatted message to the selected carrier, which then delivers the message to the recipient’s mobile device. The entire process usually takes only a few seconds.
  1. Message Termination:
