Mass SMS or the term generally called SMS Broadcast is a method of sending SMS to many numbers from one source or server with the same message content. Given its one-way nature, this type of SMS is very suitable to be used as a form of monitoring such as providing information to related parties. Partners in this activity are teachers or admins who record information to students or parents related to everything from the school.
