Wholesale SMS requires use of specialized software that sends messages to provided phone numbers. Depending on the type of software, the input can be provided by uploading within another desktop application or on the software vendor's website. Most software is capable of sending messages internationally as well as scheduling messages in advance. Some systems are even capable of removing duplicate entries, and others can also validate a mobile number before a message is sent. The message will be sent out to each phone number exactly like any other SMS; however, it will include a sender ID by default so that the recipient knows where the message originated. As an added bonus, the recipient is capable of sending responses to the system.
Using Bulk SMS is one of the easiest ways to reach many users at once. Furthermore, it is less expensive than voicemail and more effective than an email. This is because it is much easier to send one message to multiple users as opposed to placing actual voice calls.
