Or you have Good NEWS for your friends/family?
You can easily do all these and even more with “Bulk SMS Sender”, an open source android app that helps you send SMS messages to large amounts of recipients.

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.

    @Marius Danila, First, you need to create a .txt extension file and store it in your mobile memory. Next, go to the application and select that file then write msg and click on the send button.
    Yes, you’re right the application we developed is in Android with Java programming language.

    Where (what folder) does the phone number txt file need to be placed for the app to find it? There are no files listed under Open.

    Hey Sunny,
    In order to import this project in Android Studio you need to downgrade your gradle version and everything should be works perfect.

  7. hi Shehryar
    would like to use this and delete sms in log on android – i think this would be perfect otherwise everything stays on phone
    i cant get this to work in android studio – it wants to migrate to gradle but i dont know how

  8. Kindly add a feature in this app, that the app should be able to open the contact list and the user can choose multiple contacts and then the app generates the selected contacts list automatically.
    Thanks 🙂

    • Good Suggestion Safdar, Shehryar Brother well done!

      Can you add a feature to check the contacts lists and if numbers are available on whats app for sorting that list separately for whats app marketing!

  9. Thank you Shehryar Khan,
    excellent application 🙂
    Keep up the good work.

  10. I’m trying to use the application but it won’t load my contact list or let me choose the folder to pick contact list file

    • Hey charleo,
      You have to upload contact list manually from your computer or any other source and make sure file extension is .txt.

      Best Regards,
      Ahsen Saeed
