Clash-Media will design and host advertising campaigns and consumer offers to allow 3 to distribute free sim cards to people who express an interest in joining the service.
3's move follows pilot campaigns by Orange and T-Mobile previously run by Clash-Media.
Clash-Media UK managing director Luke Pursey said proactive online lead generation will allow 3 to attract new customers who are directly interested in changing their mobile network.
"The bottom line is that every single company needs sales leads to survive," he said. "OLG (online lead generation) as a sim card distribution model enables 3 to target the most responsive audience and not waste time, money and resources contacting uninterested people."
