DALLAS (CBSDFW.COM) –  Beginning today the U.S. government is ordering airline passengers to leave the recalled Samsung phones off the plane.

The Note 7 is considered “forbidden, hazardous material.” You won’t be able to board, until you get rid of it.

it’s an unprecedented crackdown on a phone. Samsung’s problems have been explosive.

“We were pre-boarding and they said if you have a Note 7, it’s been banned,” says passenger Amanda Fox.

The phones are not allowed on any commercial flight or cargo flight. They also cannot be packed in carry-ons or in luggage.

The Government issued the ban after several reports of Note 7’s catching on fire in hands, in cars and last week, a fire sparked an evacuation on a Southwest flight.

That’s why Joyce Ellis is hanging onto her flip phone, and offering some friendly advice to Note 7 owners. “Obey the rules, look out for yourself and think about your fellow passengers.”

“For a phone to possibly explode, it’s really scary,” says Allison Sweet.

If a flight attendant spots someone with a Note 7 during a flight, they’ll be asked to power it off, to prevent any problems.

Individuals who try to travel with the phones may face fines and criminal prosecution.
