[/caption]United States (U.S.) is now using a new national warning system. U.S. President Barack Obama would send short messages or SMS directly to mobile users in the event of an emergency.
A free service called PLAN (Personal Localised alerting Network) is scheduled to be tested in New York later this year, and immediately available to all U.S. residents in April 2012.
Various warning like terrorist threats, natural disasters and other emergency messages will be sent by the operator AT & T, Sprint, T-Mobile and Verizon to all mobile phone users.
"PLAN can make a big difference during disasters such as hurricanes tornadoes that recently hit the U.S., where every minute and even second additional warning could make the difference between life and death," said Julius Genachowski, as chairman of the Federal Communications Commission.
Quoted by AFP on Thursday (05/12/2011), the message will be delivered to mobile users in the areas of potential threat, not to all mobile phone users.
The shape of the warning message would be along the 90 characters or less. There are three types of warnings, the warnings delivered by the President, involves a real threat to safety and warnings for the kidnapping.
