What is Bulk SMS Sender?

Bulk SMS Sender is really small in size but not in purpose. It’s a powerful open source Android application that allows us to send customized SMS messages through their carrier network to all contacts that are listed in a Text input file. Bulk SMS Sender can serve for mass delivery of holiday greetings, as an effective marketing tool and more.
Bulk SMS Sender reads a list of contact numbers from a Text file and sends SMS to all contacts one by one. It can be used for many purposes. e.g Educational, Commercial, Learning, SMS Marketing etc.
