Does the outgoing message tie up school telephone lines or Internet access?
A No! If the outgoing message is sent via mobile phone, the school phone lines are unaffected. And if the outgoing message is sent via the Internet, the Internet connection is not kept busy by the process. The message broadcasting takes place at a central location away from the school. The speed of the school Internet connection is not important as each text message is about 2 lines of text, typically a couple of seconds.
