There are different types of GSM-devices: from GSM-alarms for homes and cars to industrial controllers, remote-controlled electric sockets and smartwatches for kids. Also, often they are vulnerable, so GSM-devices are interesting targets for hackers and pranksters.

Also, I will show some funny ideas, which allows hackers to create small (or huge, who knows?) botnet of
