We have our own proprietary bulk sms application which enables our customer to send bulk SMS seamlessly and quickly with custom sender ID. It is developed in such a way to support Unicode fonts, so the customers can send SMS in thier regional language. The SMS can be categorized into two Transactional SMS - Can be delivered to all numbers all the time (24/7) Promotional SMS - Can be delivered to all numbers between 9am to 9pm except DND numbers The main advandage of using SMS service is the receiver need not require internet connection or additional installation in thier device since other online messaging services require internet at both end. But internet connection at sednder end is mandatory.
