What is Bulk SMS Message?

Bulk SMS messaging is a legacy description for application-to-person SMS messaging services. It refers specifically to the sending of large number of SMS messages to the mobile phones of a predetermined group of recipients.

Today the application-to-person SMS messaging services have evolved to include bulk SMS messaging alongside the sending of single messages (such as one time passwords and delivery notifications), interactive messaging (such as group messaging services), and incoming number services (such as mobile marketing campaigns, voting or information lines).
