After two years of planning, the company began operations when the founders completed a $131,000 share purchase in May 1982. The firm took over paging company Meta Systems in October 1982 and then raised $9 million in its first round of financing, managed by chief executive officer, Orhan Sadik-Khan and
Kevin Kimberlin. Since 92% of the world population had no phone service at the time, Millicom promoted mobile technology on a global basis. To do this, Millicom created joint-ventures with local and strategic partners. On 13 December 1982, a joint-venture with Racal Electronics was awarded a cellular license for the United Kingdom. To enable Millicom to earn its 10% royalty from Racal-Millicom, a controlling shareholder, Stenbeck commissioned a startup with three employees,
Technophone, to develop the world's first pocket-sized mobile phone. Highlighting its plans to offer the Voice and Data phone (predecessor to the smartphone), his Racal-Millicom joint-venture was renamed
