It will take so little amount of time to send the SMS to all the recipients. But one important thing needs to be focused. Since the mobile phones are not capable to receive the text message of more that 160-characters (excluding the LMS or Long Message Service), the body of the SMS should consist of 160 characters at most. Now if the recipient wants to reply the SMS then he has to use the SMSC or the Short Message Service Center of his own service provider. Now in these improved days of technology a Short Message Service Center MULTIGATEWAY is placed between the origin (that's the Bulk SMS sender's computer) and the Short Message Service Gateway. The function of this SMSC MULTIGATEWAY is to make the transmission of the SMS faster. The servers in this system are generally connected through HTTP or UCP Commands.
