How to use the Start-Stop service?
airtel customers can SMS 'Start' or 'Stop' to 121 (toll free). An SMS is sent acknowledging customer's request & advises them of the next step. If the customer sends 'Start' to 121, then the service checks for all the subscription services not subscribed by the customer & presents those services through an easy to understand & interactive menu. However if the customer sends 'Stop' to 121, then the service checks for all the services subscribed by the customer & presents them to the customer for further action.

To subscribe to a service or un-subscribe from a service, the customer has to reply to the menu message with the number mentioned against the service. Once the system receives a response from the customer, a confirmation is sought to avoid any confusion, post which a service is Started or Stopped.
