ST. ANTHONY, Idaho — A school district in southern Idaho has joined education officials throughout the state in banning the use of cell phones.

The Fremont School District will now enforce a policy prohibiting the phones from being used in schools and on buses.

Superintendent Garry Parker says the district acted quickly, approving the new rules last week when students began their first day of classes.

Parkers says the district has already tried alternative methods to discourage the use of cell phones, such as using a device to scramble cell phone signals. But that measure became disruptive, Parker says, because it interfered with other electronics used by school officials.

Earlier this year, the Coeur d'Alene School District in northern Idaho has also adopted a strict ban on cell phone use.
