Bulk SMS, is useful when the same message is required to be sent to multiple recipients.

This service is reliable and stable with instant delivery to handsets at a throughput of between 10-20 messages per second.

This service is primarily aimed at non-critical marketing campaigns.

Other than price, an additional differentiator of this service is the ability to brand the originator of the SMS message being sent. IE, when looking at the message on the cell phone the recipient will see that the message is from the brand, (eg: flysaa.com), rather than just a number. Of course, the recipient will not be able to reply to the brand, but must read the actual SMS message for contact information.
