I found this interesting:
A few days ago a Reuters report described how Africans (and others) have devised ingenious methods to communicate with cell phones without incurring charges. This is accomplished by beeping: placing a call and allowing the screen on the receiving party's phone to flash for long enough to identify the caller. The person placing the call then quickly hangs up, hoping that the call recipient will phone back.
Rules of Beeping: Sciam Observations
