  1. Excellent script!! Works like charm, just add a comment to the user to configure the system type. Most of the providers use smpp as the system type & unless specified the message will not go.

    Thanks Again!

  2. This script is excellent and its excellent work for me. Would you please help how to received the SMPP sms using PHP.


  3. Hi, one question can I send an sms to several stored phones in a database list? What time should there be for each other for the queue to work?
