The homepage, or “dashboard” is already being used by brands in 3’s Austrian operations with campaigns running for Volkswagen, Suzuki, Kia, Peugeot, Mazda, Honda and Land Rover.
The Hutchison Whampoa-owned mobile operator is yet to sign up UK advertisers, with the initial deals expected to last until the end of the year.
The dashboard, which launches every time a user connects to the internet, will be visible to more than one million broadband users and receives more than 30 million impressions every month.
Neil Andrews, 3 UK head of advertising, says: “Our mobile broadband offering is seeing a huge amount of uptake. This new opportunity presents brands with the opportunity of getting in front of a large target audience in a bold and visible manner.”
In May, 3 signed an ad deal to sponsor Original Comedy on Channel 4. The idents centred around poking fun at what people love and hate about using the internet.
