The six foot tall flashing phone will remain in situ until 20 June. It will feature a large ‘Stop’ button that, when pushed, will light up the phone and allow consumers to vent their frustrations regarding spam calls and texts.
Passers-by will be able to sign up to the Calling Time campaign at the event, as well as explore the brand’s new complaints webpage.
Following its stint in central London, the activation will visit Glasgow Central station on 26-27 June and Manchester Piccadilly station on 3-4 July.
Richard Lloyd, executive director at Which?, said: "People are sick of being bombarded with nuisance calls that invade their privacy and waste their time so we’re giving people in London a chance to vent their frustrations and support our campaign.
"The government knows what’s required to tackle nuisance calls so we need to see more sustained action, with senior executives held to account, to help put an end to this everyday menace."
