Bulk SMS - How to send

What is bulk SMS messaging?

Bulk SMS refers to the sending of SMS messages to a large number of recipients via an API (like SMPP).  Typically, bulk SMS implies the company sending the messages is sending the same message to all recipients, even though it’s possible to add personalized elements.
