Students are flouting South Australia's new ban on mobile phones in high schools even posting tips on how to thwart the new rules, the state opposition says.
The opposition has pointed to a number of videos by students on social media, including one ridiculing the ban which has been viewed four million times.
Education spokesman John Gardner says the government's policy, which came into force this week, falls well short of the promised ban with an extremely broad range of flexible exemptions.
He says schools have also been given no support from the state government to cover the cost of implementing the ban with some forking out thousands of dollars for lockable pouches.
"Banning mobile phones in high schools is a complex task, but these social media videos demonstrate how ill-prepared (Premier) Peter Malinauskas and his Labor colleagues are for managing phone usage in schools," Mr Gardner said.
"I have no doubt the videos brought to our attention are just the tip of the iceberg. Labor's half-hearted ban in high schools is clearly falling short, and students are taking advantage."
Education Minister Blair Boyer said it should come as no surprise that some students would try find a way around the ban.
"It actually highlights why we need to do something. We know that kids will try find a way to hang onto their phones," he said.
But the minister said feedback from schools was overwhelmingly positive with a number of schools reporting children spending more time at breaks exercising and talking to each other.
Under the rules, student phones must remain switched off or in flight mode, and out of reach all day including during breaks.
Schools may use lockers, special magnetic pouches or other ways to secure phones.
Some exemptions will apply including students who need their devices because of medical conditions.
Mr Boyer said the government expected "bumps along the way because no one likes to lose their phone".
"We'll do what it takes to make sure the policy works," he said.
