Your message will be delivered a 1 unit per page of SMS through what we will call the corporate route. This route does not have the capacity to deliver messages to phone numbers that are active on DND list. However, phone numbers that are not on the DND list will receive your messages.
So, give it a try whenever you are low on SMS units and your units would be effectively managed for phone numbers that are not on DND.
Please watch the video below to see how this works.
