Russel Tarr, owner of Classtools.net, has developed and published a bunch of great tools over the years. One of my favorite of those is the Fake SMS Generator which Russel developed almost a decade ago and is still going strong.
The Classtools Fake SMS Generator is free to use and does not require students to register to use it. In the video below I demonstrate how to create a fictitious text message exchange between historical characters.
As I mentioned in the video, the Fake SMS Generator could also be used to create visuals for lessons on cyber-safety and etiquette.
