The campaign, created by Mother, shows a young boy aping current business training techniques to show Orange phone users how they can get more out of the handsets.
It was criticised by the National Family & Parenting Institute over concerns that it went against a government report on the potential health risks of children using mobile phones. However, no complaints were received about the campaign by the Independent Television Commission.
The briefing today is to be hosted by Orange vice-president of UK brand marketing Jeremy Dale and will be attended by a number of journalists.
However, a spokeswoman for Orange denied that it was to defend the "Learn" campaign. "We're doing a very informal lunch for journalists to present the results of the 'Learn' campaign," she said.
The briefing would include sales figures and customer response to the campaign, and will be attended by journalists from the nationals, the marketing press and the mobile trade press.
Orange's latest advertising has had a thoroughly rough ride, coming under attack from all sides.
The advertising that preceded the "Learn" campaign was no less controversial, with former Orange CEO Hans Snook describing the ads, which featured a very literal interpretation of a hard-nosed businessman, as "the worst things I have seen".
Mother won the Orange advertising account in October 2002 after Lowe resigned the work. Dale has previously worked with Mother when he was at ITV Digital, where Mother's Monkey advertising was widely acknowledged as the most successful thing about the defunct television service.
